Cool, thanks for clarifying.....Just want to make sure....Great results

PS. Yes, this kind of torque is bad for your transmission and/or clutch.

True enough.....whats your opinion on the max amount we should put to the AT on the 335i?

For normal driving, around 350#/ft or less.

Exactly. I try to avoid exceeding 350 lbft.

Terry isn't it time for the JB-Pro where you have a toggle switch for 91,93, and Race gas maps?

A new version every day isn't going to make people happy.

E90 335i · 12-01-2007, 09:51 AM

Nice job, Terry! Keep up the great work and I am looking forward to the JB2H.

Actually its all modular. The base JB2 is a safe and reliable tune for 91-93 octane. If you run quality 93 octane and/or have extensive exhaust mods, the hot pill snaps in to the JB2 for ~12rwhp gains. If you want to run race gas the race gas switch lets you get another ~20rwhp on top when used with 96+ octane.

Seems simple enough.....

Terry, this might have been asked, but what is causing that bump in the curve at 2600rpms?? It seems to be the same on all your dyno's regardless of which tune you were running.

Looks good though!! Nice work.

Thanks! I think it was torque converter flash (I have an auto).

Looks like the stock graph has that too (Page2), on the other graphs it is exaggerated more

Terry congrats those great numbers, keep up the good work

. Next time I go to the track I like to run the JB2 with the pill on 93 octane to see if I can get high 12's

those look lines look really bumpy and not very linear...where is the smoothness?

hotrod182 · 12-01-2007, 11:11 AM

With the Steptronic going into lockup even at full throttle, the transition will show on the graph.

Are you kidding? These are the best 335i dyno graphs I've seen in awhile. The ~4000rpm dip is the normal VANOS event.

E90 335i · 12-01-2007, 11:14 AM

Those are some nice looking graphs. Not sure about the bumpiness. Bumpiness is his stock graph.

Marcos, you and I both will go to the track once we get our pills. I'll also have a little VIP magic under the hood.

Great meeting you!
