JWT ECU with SC + MEVI + 5spd Conversion question
So how much is the JWT SC Program going to help my low-end and midrange power and dyno and track numbers?
Finished the 5spd conversion 2 weeks ago....just finished breaking the clutch in over the last few days and boosted a bit.
9 PSI in 1st, 7 in 2nd, 5 in 3rd.....never have figured that out. It's been a year...I gave up.
Anyway - how are the gains with the JWT Added? Anyone have any before and after Dynos with that as the only change? Anyone have timeslips also?
Have to say, 1st gear is completely useless at WOT, and the car isn't as fast as I thought it would be. 5spd is definately better, but not what I was hoping. (although I did expect 1st gear to be worthless, I more am talking about the other gears)
Thanks!

sorry for the off topic reply, you seem to want a bit more power, try the Fidenza flywheel, you wont regret it trust me on this one.

True.
I know it also comes down to the fact that I haven't driven a stick in 8 years up until lately.....My shifts aren't exactly super fast.
But I'd rather granny shift for now until I am 100% confident in my rev-matching abilities....I'd hate to blow a tranny at this point from hard/bad shifting.
Anyway - still interested in knowing the gains from a JWT SC ECU - anyone?
