Hey guys I need a little help! I am looking for a 90mm throttle body for my 2012 Z71 6.2l. I already have magnaflow catback exhaust, vararam ram air intake with a Diablo Trinity tuner. I also have a 3in lift with 275/70/18 cooper st max tires and still getting 17mpg and running just under a 15second 1/4 mile run on the street not track. Can anyone help me out finding a 90mm throttle body?
I ordered an ACDelco 217-3153 throttle body for my 2010 Silverado 6.2 and I got two DTC's p1516 and p2101 and a reduced engine power light I dont know why????
