So I just got my car back (Which isnt fully tuned and running rich) and im noticing that the car likes to kick and jump at certain RPM's. Im going back in for fine tuning in a couple of days, but Im just wondering wat causes the car to jump/kick like that. Thanks.

Usually due to a fuel curve that isn't smoothe. It will hit lean or rich areas and jump back and forth.

Bingo. Bucking is usually a leaner condition most of the times. Whatever you do, just keep it out of boost.

Yep, it is usually a lean misfire that causes a little cut.

 

Ahh icic, ok, thanks for the info
I'll let my tuner know.

My tuner also told me that he set the car to run rich for the time being...
Cuz even at idle, my car has trouble idling and also stalls on its own sometimes haha.

 

run from that tuner dude

 

Its not his fault that he cant tune it. One of my silicone couplers for my IC piping is a POS( Turbo to IC Piping) and it keeps blowing off at High RPM's. Im replacing that this weekend and going back in for fine tuning. Plus, i have crappy plugs in the motor rite now, that might add to it running like crap haha. But my A/F ratio is pretty consistant..i think it was at 11.2? I forget.
