One of may considerations but yes, I believe timing is more aggressive on the JB3 though I have beat the crap out of it and see no codes or knock activity of any kind (even in the God awful weather with no mods).

I would say a 7 - 12 whp difference in power for me even without additional mods by moving up from Stage 1 to Stage 2 (dyno tested) |

Too much money spent on dynos and not enough spent on track days. Kelvin you must get your BMW software updated to 33.1+. You'll have no need for a "lag-fix".

Im gonna have to slightly disagree with you on a few points here (I have Procede too): 1. riding the knock limit doesn't always make more power, as you can see when the car pulls timing due to knock it overcompensates on how much it pulls out and then will put some back in. This could lead to a loss in power as too much timing will be pulled, unnecessarily. It's hard to say overall which is better for power - not staying close to the knock limit or hitting it and dipping down repeatively. 2. more boost definitely does not equal more power. Timing seems to play a much more critical role in the car. I have deduced this from the 100s of drag strip passes I have made. Turning up the boost can definitely lose power as timing is being pulled. I think the JB is running less boost up top, at least that is what I gathered when I raced Brianhn1. Granted I was on an old stage 3 race gas map (I'm stage 1, non-canbus) so this is prob not a fair comparison, but I was holding boost to redline and his car was dropping boost from 17 to 13 psi. I was holding about 16. I'm sure my car was pulling massive timing up high, causing my trap speeds to be lower. (I did trap the same as him one pass, but my car was inconsistent. I think that shows the car pulls timing sometimes, and that one time didn't even though I held boost to redline). I'm not arguing which one I think is better, I drive with the Procede, probably always will. I just wanted to give an alternative perspective to what you said.

JB Maps 2/3 are probably the equivalent maps with 12-14 psi stated by the tuner. Map 5 is significantly stronger than stage 1 and IMHO more comparable to Stage 2 than Stage 1 But regardless, Maps 4/5 do pull harder in the top end than Procede stage 2 based on my recent driving experience of both. However, as stated by others, both tunes are very good at what they do and are approaching each other in some ways, yet retaining their essential character at the same time. JB3 is about power and fun factor while Procede is about driveability and retaining the fundamental characteristics of the N54. Just depends on which part of the rpm power band you spend the most time in. |

Kelvin, what user torque settings did you use for the canbus maps. On stage 1 and stage 2. Im curious. Im ordering a jb3 today but Im worried about selling the procede (it would really help) because they could come out with stronger maps soon or maybe not. Im running stage 1 at a ut of 74 and 78. The 78 is really strong and smooth but apparently jb3 is just a more powerful tune.I'll find out in a week. my decision is keep the procede and the jb3 or sell procede and fully switch (more funds to get all the jb3 goodies). Will procede strike back or no?????

thats what Im thinking. Its tough though. I hope the next one gets a bit stronger. I know the procede can do more. Like I said at ut 78 on stage 1 its running awesome. I just want a bit more bite.

I agree on the track stuff and will be ready soon... I bought a Bell Helmet exactly 2 weeks ago but I want at least the intercooler installed before I go play with you big boys in the summer heat. Track tires and a second job are next. |

I would still get 33.1, it's different regarding wastgate operation. Trust me, you won't need the intercooler for your first few times out. Get yourself a set of cheap kosei 17s and throw Dunlops stars street tires. Wait for VKs $500 I/C.

I think both tunes are great and I know that one of the future adjustable parameter that Shiv is working on is Active Timing user adjustments which means that you will be able to turn it down and let the DME adjust closer to the knock limit and go for dyno, street and track glory. As it stands now, the JB3 is simply faster. Race them side by side and I am confident this will be confirmed over and over. |

I know, it seems the higher modded cars/maps are worked on more. thats what shiv tests them on so..I would love to feel the difference.

Judging from Vk's oil cooler, which is sitting in my garage, quality isn't sacrificed. Some vendors could learn a thing or 2 from Vince's business practices. He is a pleasure to deal with.
