Help

 

Um, first off where did you get the kit?
Did you get the walbro from ebay? Lots of fakes floating around there.
Those injectors are pretty small. 550-600cc probably should have been the minimum.

Did you get the car tuned? If you didn't those injectors aren't going to work right.

 

haven't got it tune, just base tune on steet driving.
does clutch have to do anything with that?
still running stock clutch have and car 77,000 mile

 

clutch has nothing to do with it.

it seems the tune is the culprit. it could be your throttle position / injector map. your injectors need to be dialed in your tune (delay, flow).

 

alaite gona get tune soon thanks guyz
