My JB3 1.22 feels NA compared to Procede V3 after a thorough driving impression. That doesn't mean it's slower though, read on.

I have an 07 335i Sedan 6MT with the JB3 1.22, and my friend has an 07 335i Sedan 6MT Procede V3 with the latest maps, as well as another friend with a Procede V2 on an 2/08 built coupe.

Last night on a closed section of road we did a few highwaypulls to see how the 2 (3) cars stack up, as well as switched cars between the two of us to confirm our feelings.

First impression is like the title says, the car with the JB3 feels like a Naturally aspirated powerband compared to the Procede. The Procede has MUCH more power down low around the 2500-3500 rpm range. Basically the power on the Procede came on really strong at around 2500 rpm where the JB3 car didn't have a chance. However once we were over 4500 rpm things were nearly equal.

There is a Valid arguement that under 4500 rpm you can allways downshift and you are back in the powerband, but under normal driving conditions where you are using that lower end torque, the Procede is much better.

These "feelings" of lower power were backed up when we did a few side by side comparisons.

First we did from 40 mph both in second gear- pretty much a burnout contest with the below freezing weather

Next we did just under 50 mph, JB3 starting in 2nd gear, Procede starting in 3rd - pretty much equal

Then 50 mph, both cars in 3rd gear, the Procede car ran away till around 4500 rpm on the JB3 and then the cars stayed equal

Last 65 mph, both cars in 3rd gear, pretty much equal through 3rd and then even 4th gear.

All in all I'd say at the 1/4 mile the lack of low end power might actually gain some traction for the JB3 and make it easier to drive out of the hole, but all in all the Procede does make a lot more power on the lower rpm range.

I hope to get some more comparisons in when the weather is better.

great review! JB3 feels like a N/A huh! Thats the first I have heard of a description of a JB3! Congrats!

What map was this?

If you were to read the thread you would see it's not exactly a complaint.

Sorry, I was on Map 4. I have no other mods, and for the 93 Octane I run it seems to have been the most appropriate map to use.

good review. JB3 does feel like NA down low, by design, but once it hits 35k it shoots out like a cannon ball, again by design.

i think it's more or less personal preference as we have seen both cars are pretty eqaul in performance no matter what each party says. however, you can either go map 6 (probably more inline with V3's stage 2..which is better with supporting mods), or wait till JB3 1.3 comes out when it will give you more low end torq to play with. do you know what ecu software u have?

The jb3 routinely shows more low end torque than the v3 on the dyno. See recent comparison graphs posted by Kelvin1000. The difference is that the v3 actually puts all that power down in the real world. Not only during a single gear WOT dyno-style pull. That is by design.

So its true... it doesn't just "feel" faster in the lower RPMs, it actually IS faster, even though the dyno graphs show similar TQ numbers

Yes, if the manufacturer said this...it must be true !

Glad we made the runs very close runs too.

The JB3 feels wayy different than I expected, Very NA feeling compared to the Procede. I am glad to have driven it. I don't think I will give up my procede for it. (Its a great bang for the buck don't get me wrong). But I love the low end torque feel and smoothness of my procede. Cant wait to add some DP's and see how it does next. Try to get some vids next time too.

All good runs, very close (within car lenghts of each other) on the 3 lane wide road (closed highway of course )

yeah the V3 is better in any way , i should sell my tune after reading so many nice reviews about the V3

then people will likely jump ship again when jb3 1.3 comes out. it's like that since the begining.. v1, JB1 - to 2 to 3, etc.. etc.. might as well just stick to one and let the tunner develope.

trust me, when one comes out better in some ways than the other, the other tune will one up on it again.. then back and forth. that's the beauty of competition

was being sarcastic just get really tired sometimes....

^ Just trying to post some real world review. Not just a "feeling review".
All 3 cars were very close, door to door or 1/2 car lenghts kind of racing really. I dont think you can go wrong with either tune really. We canTry to get vids on the next runs, this way its more entertaining at least

Xander bought the JB3 because we (the other 2 cars) have Procede's and that is all we have ever driven, it was a comparo/test that I am sure we will keep testing as more parts/mods and miles are added by this spring/summer.

Its a great benchmark for us locally to keep testing against each other by roll racing in 2nd & 3rd through 4th gears to see the differences (trying to take traction out of the equation). We also swap cars often to get a feel for each others cars/programming.

I am glad Xander bought the JB3 for comparisons sake. Its going to be a fun summer.

i think you did a very good review! Keep it coming! Wish i had some buddies like that with the same car to do some racing together :-(

my friends hav v3 revII. i'm also thinkin of gettin the jb3 to be the oddball out

nice write up op!

Its good to have at last a comparison on the road.

Many thanks Xander

Very nice comparo.

Just curious which stage of the PROcede were you running Jeller, and did you turn up the user torque setting from the default?

Xander, on 93 Octane (and especially in below 85 degree weather) you should of been running Map 5 or 6, it gives about .75-1.0 psi more boost below 4000 rpms and has a bit more power on the top end too.

You guys should go back to that same road (closed section) and do the runs again with PROcede on stage 1 default UT settings (or stage 2 default if that's ok on 93 Octane tune only) and JB3 on Map 6. Would be interesting to see those results too.

What was the outcome of the older PROcede v2 car by comparison?

Oh and lastly were all the cars stock other than the tunes?

Are all of you on stock 18" wheels and tires?

I believe Xander was on map 4

I (Jeller) running Procede (old version upgraded to v3 pnp NOT Rev II) with user torque settings at 90%

I would like to see my car on Stg 2 map with user torque about 94% max vs. his Map 6. That would be another great comparo.

Older Procede car (V2) pulls on both of us from the start, he was letting off due to poor tires/not comfortable in cold weather. His user torque settings are 94% tapering to 92%, he has an 08 coupe.

I have to say the older v2 is no joke, his car is fast for old maps. I thought for sure once I upgraded I would edge him out, but have not once since I upgraded to V3 from V1 for me. Makes me curious as to why the older v2 is more powerful ? or is the user torque table with incremental adjustment a better tool ?

Xander = stock 162's with snows
Jeller = Rial Salerno's 17" with snows (tires one size too big)
Sam (coupe) = Stock wheels and RFT's (bologna skins for tires)

We are all very close, no major differences in weight/size.

How did the cars stay equal with you starting in 2nd gear and him in third taking off from a 50 mph roll? These tunes almost perform identical so how didn't the tune that was in a lower gear didn't jump ahead. A little more low end power is not gonna do that. A friend of mines has a 460whp GTO & I had a 346whp GTO. We did a couple of rolls with him giving me a edge. I would roll out in 2nd and him from 3rd. The outcome was the same everytime I would jump ahead and hold it into almost until the end of 3rd then he would come soaring past me. So how could you start off in a lower gear and didn't pull on him a little?
