I looked at the dyno sheet for the 135i it made 253 hp/ 267 trq baseline and then 313hp /354 trq on cobb stage 1 aggresssive 93 oct. The op 's 335xi made 247hp/267 trq for a baseline and then 274hp/308 trq on stage 1 aggressive 93 oct. So as you can see the baseline #'s were very comparable , but very different on the same cobb tune? Is there any reason for this? Maybe Chris from EFI can respond. I'm not trying to stir anything up just want to know why the tune was more effective on one car over the other even though they were both stock.

The biggest difference is the AWD AUTO vs. RWD 6speed setup, your parasitic losses are drastically lower, hence getting power and torque to the ground with much less effort. That particular 135 was tested on the hard side, making 16psi on a stock setup, but scaled back after. Obviously, monitoring the car while doing this is ok, but extended hard abuse without watching over things can result in a loss of power or damage, and not something we recommend.

Cobb's "Aggressive" tuning is aggressive based on OTS tuning. I'm going to quote Rob Irish from Cobb on an email conversation we had today:

We went out very conservatively on the first pass not feeling very comfortable with the timing corrections the ECU gives. Added a bit more to the Stage 2+ maps and will be adding that to the stage 1 and stage 2 maps. Still should give you plenty of room to make gains.

On Pete's car, I added 1* of timing from peak torque to redline, and the car picked up nearly 14hp at the same target boost level. Cobb Maps are conservative, rightfully so, they have to support a very broad variety of fuels and driving conditions, this is why custom calibrating the car can make for a much better experience, you are getting the car dialed in to how YOU drive, and what YOU want.

Hi Everyone, my name is Josh and I own and drive the 135i that EFI Logics tuned. They had my full consent and have done nothing but provide me with excellent, consistent and fair business for over 5 years with all of my cars that I have owned. I fully recognize everything that Chris was doing with my car. He kept me updated the entire time he had the car and I feel 100% comfortable. Chris is not only a skilled tuner, but an honest individual who has gone the extra length to ensure I was taken care of.

To put things in perspective for you, let me explain to you the lengths that I speak of. I had a 2007 STi that ultimately had a motor failure due to a cracked ringland. I brought my car to EFI Logics after hearing great things about them and having numerous bad experiences with dealerships and performance shops all over New Jersey, Connecticut, Rhode Island and New York. My car was quickly diagnosed and and they informed me of the wait time until they would be able to take my car in, rebuild the short block and install it into the car. I decided I wanted to do things right and so I left my car there and after a month's wait I picked up my car rebuilt and ready to go. I drove the car to Rhode Island from Connecticut and it died in the parking lot. EFI Logics had the car shipped back, inspected, fixed and driven back out to me within 1 week. All that ended up being wrong with the car was a small shard of metal lodged its way into the AVCS controller that controlled the timing of the intake camshaft. To me, THAT is how you do proper business.

They made my STI a monster that was indestructible and took punishment beyond what the average car will ever see. Their expertise is second to none and my 135i has been fantastic since the day I got it back. The power delivery is smooth as glass, the peak power is brutal and its drivability has been further improved. If you had not known the car was tuned, I doubt anyone would be able to tell minus the momentous power thats on tap from your right foot.

Chris, I've heard nothing but good things about your shop and tuning even though there's a huge wait for work. I came by at one point for you to install my FMIC, but the wait was 6 months and I couldn't wait. Would you PLEASE tune my OBD I Mustang? You're sooo close to my house.

Aww man, asking me to tune an OBD 1 Mustang is like asking me to take a time machine back to 95. I haven't tuned one in years, although I still have my old chip burner still, along with my Sneek Data acquisition tools. You would have to catch me on a really SLOW day to get me back into that seat.. It's been far too long.

Can I put this in red and bold because it's my favorite?

Been dealing with Jimmy and John @ The Shop for a while now in regards to a few different cars. Great group of guys and very knowledgeable. They do everything from engine builds and fabrication to protunes, hardware installs and routine service. Very happy with the work I've had done there.

It does explain SO MUCH though....for those enjoying the popcorn, TheShop is a direct competitor of EFILogics in the Subaru/Evo world.

But remember, there's no conflict of interest here....wow, people never cease to amaze me.

I've been on forums probably longer than you have been alive so spare me the 'you're new here' crap...but thank you for reminding me why forums chase off all of the good knowledge in the automotive field. You MUST be an expert, you have a methanol kit....who installed it BTW? I'm sure it wasn't you.....

Pete you didn't know? Someone should have told you. You cannot be a Super BMW Mastertech or know anything about anything until you reach 100 posts minimum. 99 of which have to be bashing people. Then you will reach I know everything about everything status.

Also one other thing you forgot to mention is that Pete's car is an Auto vs the 135i is a stick, I would assume, correct me if I am wrong. This will also play a role in the #s being different.

To get back OT....yes, it was a completely different car. It still isn't the CTS-V I was considering but I needed to stick with AWD and would rather invest the additional $$.

It's not even about taking it to redline, the torque curve just feels natural even when driving like a human.

Driving her car this week but I'd like to see what if any changes there are to highway MPG.

Very nice. Its a subtle difference (from what we are used to) but fun and definitely worth the $$. Its no 600rwhp+ car, but its also a DD.

I really didn't pay attention to MPGs when I did the tune. However I usually get around 28-29mpg on the highway cruising @ 75-80, that is also with no cats.

Chris from EFI if your still out there I just want to ask you a couple of questions. First of all I met you once at your Oct. 1st dyno day. I was always told that your a great tuner by a couple of subi guys that I work with, Travis Mastrogianis and Matt Linster. Well at your dyno day I dynoed my evo8 with full bolt-ons and it made 348 hp/ 350 trq, a week before that I had my car dynoed at Pruven performance (dyno-tuned on their dyno-jet) it made 387hp/365 trq. Now I know the dyno-jet is going to read higher,but heres my point - I also brought my 335xi there and stock it put down 259hp/270 trq . I then flashed the cobb stage 1 aggressive 93 oct. map and it put down 327 hp/360 trq, thats a 68 whp gain. I know this is on a dyno-jet , but the 335xi you recently dynoed only gained about 27 hp before you worked your magic. Also I know that your shop 535xi gained more also. So my question is if I were to dyno my 335xi on your dyno would the gain be closer to 30whp or 60 whp? I would deff. be interested in you pro-tuning my car in the near future but I would like to get a fmic and intake first. Thanks for responding Chris.

Thanks John

[Steedman99]

Grats Pete! Thats a killer DD..And nice work once again form the boys in Bethel..

[Szemenyei]

I have had my car dyno'd at EFI twice. Both at the JNA Dyno Days that they had there. I had it dyno'd once stock with only dci, and once with stage 1 and dci. I will scan my dyno sheets and post them up later on. Cant wait to go back on the dyno again to see what my car is putting down now Stage 2.

Were you there on the Oct. 1st dyno day? I remember seeing a black 335xi sedan there, don't recall if it was a 6at or 6 sp stick. What tune are you running? Well I can't wait till they have their next dyno day.

The black 335xi was mine, 6MT, I am running the Cobb OTS Stage 2 map right now, about to be Stage 2+

The dyno days are always lots of fun.

[ExpensiveTaste]

Chris would you do a dyno day for the 335xi/335i crew local to these parts. Sorry for taking this off topic Snkypete. I don't need a tune since I'm using JB4.

[CT335xi]

Szemenyei what were your #'s on EFI's dyno baseline and cobb stage 1?

[Elliott@DetailAddict]

Huge +1 for EFI.

My best friend back home with STi Limited #777 has had his beast built their and has had nothing but positive experiences with EFI.

I will check when I get home, they are on my desk and post my results here.

My car is an AT, that makes a significant difference in power loss. Also stock intake.

No worries...going OT and bashing are two completely separate things...every thread wanders eventually.

Since I've been asked - I'm fine with leaving hp on the table because I'm fortunate to have a fast car already which is pushed to the edge. I want comfort/luxury first with this car. One of the reasons I sold my WRX (and primarily because I needed an AT car). We also just purchased an 08 X5 and are very happy with it. I was looking at M5s E63s and CTS-Vs and while this car isn't as fast it costs half as much and makes enough power to get me in trouble back/forth to work.

Bought wheels/tires, AE upgrade today and I have a rear spoiler on the way....and yes I will be commenting (positive or negative) about those transactions as well. The more knowledge everyone has the better decisions people can make.

[QUOTE=Snkypete;11394331]My car is an AT, that makes a significant difference in power loss. Also stock intake.

My car is also a 6AT with stock intake, so basically we have similar cars. I'm by no means trying to bash just wanted to know why such a big difference. Like I mentioned before I dynoed my car on a dyno-jet and the cobb made a 68 whp and 85 wtrq difference. In the future I would definitely use EFI to pro-tune the car.

Hey John.. I'm not really going to go into the dyno debate, but what matters is that you did a before and after on the same dyno. The big thing here is not to chase the numbers, chase the overall gain. I can't really say why one car made more than the other, it is what is. Pruven does have a dynojet, and it does read higher than most others out there.

We are in the works for a New England BMW Dyno day soon, our marketing team is working on setting up dates now. We currently have a huge Audi Dyno Day on March 3rd, and even though we don't work on that platform, we still welcome them to our shop


Hope that helps,

Chris

Correct, thanks for that. I edited the original reply to reflect those differences as well.

Thanks, we are definitely having another big dyno day this year, maybe two, but we are going to focus a few dyno days on the BMW's as well so we can concentrate on the needs of this community more. Keep an eye out for our posts soon, our marketing guys are drawing up some events as we speak.

JB4, Cobb, Procede - It doesn't matter to us. We are definitely going to have a dyno day for you guys. As I said previously, we have some big things planned soon, and the dyno day will be one of them.
