18K miles and ZERO oil change? That's insane...when I used to have twinturbo setup on my FX, I changed oil every 2500~3000 miles with Royal Purple Synthetic...that was like my first priority to protect engine/turbos. but dang 18K miles?? I'd do an oil change every 3000 miles if I were you to save your decent ride & Turboz...especially with Procede...come on now...

so you are saying that an intake would make me gain 40whp ( to 36x whp the advertised V2 dynos.) ...i find that hard to believe.

There were three cars and one of them was a bit of an outlier or factory freak. So that makes your car to belong to the majority and to be "normal".

Unfortunately it will be YOUR problem and fault, not the dealers for being so cheap.

Changing the oil yourself is a $45 job you can do in the garage/carport in under 30 minutes.
Change the oil every 5-7K with synthetic and your golden. No reason to really do it any sooner than 5K with the quality of oils these days and don't go past 7K.

Anyway, I think you've probably discovered the reason for your low dyno.
If you redyno after an oil change and you still get a low dyno, try your friends K&N.

Especially a used N54 BMW without warranty.

What synthetic oil do you guys suggest is the best?

[hwelvaar]

Are you guys not freaking out somewhat regarding these oil changes ?

I mean, how dumb would BMW be if they would use (less quality) oil and (too long) changing intervals that would actually shorten the lifespan of their cars or hurt the performance?

BTW, according to owner's manual (at least where I live), BMW recommends Castrol oil.

I have V2 no way in hell the car is more than 340 hp havent dynod but i have full exhaust feels like a cow compared to my z06 im not modding anymore new zr1 coming out save my money for a real car.

Try no more than 330whp.
I think it was all marketing business fron Vishnu. Personally, I'm disapointed. All the dynos fron Shiv show 36x whp (with intake) and me and my friends barely hit 330whp.

Could be the 10% ethanol they mix during winter?

Trust me Shiv has said many times the intake is a big restriction on the car.
I was just with M&M doing some dyno runs, he has V1.47 i have V2 he has 2 cones intakes and i have a drop in K&N and you wont believe the different those cone air filters make. Ill start another thread and post dyno runs.

Some people have weak car engines, some have strong engines. Yours is below average. Who knows, maybe mine is too. The point is that the Procede in Shiv's car was specially tuned by him for that car whereas we all get a generic map for everything. Dont worry so much about who has the most HP. Geez.

Actually, just about every customer cars we've tested has made within a few hp of my own car with the same map and level of mods. I think the biggest contributor to how much power you will make depends on fuel quality and testing conditions (rainy weather being the worst). There doesn't seem to be much of a variance in engine power all things equal. Of course, there are exceptions. 18k miles on the original oil will negatively impact performance, without a doubt.

It was raining pretty hard that day.

I will get an oil change Wednesday and then re-dyno. Weather is supposed to be sunny and dry all week.

We'll see what happens.

335i, 6AT PROcede V2, Magnaflow Cat-back (Catless), BMC Air Filter, 92 octane, 94%

Conditions: DynoJet, 58F, 50% Humidity

SAE
326whp, 382wtq
323whp, 378wtq

Uncorrected
340whp, 398wtq
336whp, 393wtq

No stock runs.
To think that I was actually hoping for 360whp...what a joke...i'm just happy that my car put down 10hwp more than a Jb2H worth $350

Noob. WTF?

First, yours is SAE which is standard and always reads lower then STD correction as Vishnu posted. If they considering STD is better tuning FI vehicle so be it, the rest of nationwide tuning shops using SAE correction, hence accurate and realistic results.

Second, you haven't change oil within 18,000 mi .

Third, change oil, run baseline, cool it down and enable V2 and dyno again.
In addition, ask your shop to convert from SAE to STD and post both dyno here. You'll be surprised with difference between them.

Hope I'm not harsh

He did the right thing; he posted SAE corrected numbers! I agree that he is probably overdue for an oil change.

I hope in the future that this gentleman continues to post SAE corrected number and looks past the pressure to do otherwise.

Let the car adapt to V2 and Dyno. Run the software and ensure you are peaking at around 14.5-15psi.

When you Dyno, make sure you go to the Dyno with your Cabin Air Filter removed. This way you can make your runs and then since you have easy access to the ECU box, stick in the bypass plug to get your baseline reading for comparison. This only takes 30 seconds.

im sure the v2 is adapted by now as hes had it for quite some time. however, getting a baseline would be key for comparison sake with either bypass plugs (will probably be off due to adaptation) or a stock 335i.

[jahwerx]

OP, could you do a favor and post the plots - more interesting than peak numbers. TIA.

Is it possible for the engine to perform poorly (dyno less in this case) due to the above oil reasons?

I thought BMW's "free" oil change interval (as per the included routine maintenance) is either 15k mi. or 12 months? How long has it been since you've driven 18k mi?

I changed my oil @ 5k, which was too long IMO.
