Hey Guys, I need some help. Today I finished my work on the car, it's been a year long process, and I immediately have a problem. Part of my basic engine mods have been installing the Miller MAF kit, and Yellow Top i0(19#) injectors. Upon driving the car, things seemed rough, as expected. Yet my fuel milage was at 9.8 AVG over an hour drive mixed freeway and highway. Further, under exceleration, clouds of black smoke poured from the tail pipe. Considering the miller chip is designed for 19 pounders in a 173(I'm running a 525, only difference is the top speed limiter, correct?) I assumed FPR wouldn't have to be changed. Do y'all have any advice, I really can't wait till Monday to call Miller. thanks for your help!
