Help! With a 0.5" smaller blower pulley now part-throttle is too rich Hello all,
My car is a 2007 C6 Z06 with cam, YSi, 60# injectors, etc... Before the pulley change I was getting -10 in all fuel trims; now with a 0.5" smaller dia. pulley I see -20's!!! in part-throttle and idle. I tried lowering the MAF table and no good. I set the whole injector flow rate table to 7.99 (max it gets.) Fuel pressure is at around 60-64psi.
Can someone please advise on what I can do??? The situation is only in part-throttle and idle.
Thank you very much.
