bucking under sudden accelleration
Hey, i still haven't turbo'd the car but i notice while at slower speeds (more noticeably) if i stab at the gas it bucks furiously than goes. Same if im cruising, and i push down to accel a little.(at higher speeds it shakes a little)

Sounds like AE to me, the map 'may' be fine... it could be way fat, or way lean when you hit it, a datalog will show that, but AE is likely the fix either way. Read the AE section of the MegaManual or MS1 Extra manual for tuning info.

for me, this only happens when my cruise map is too lean. I set my cruise to 16:1 above 3k, 15:1 2.2k-3k, and 14:1 between idle and 2.2k. AE seems to help with throttle response for me, but I suppose I dont often "stab" the throttle. I tend to ease into it even when I wanna accellerate quickly.
