Well, got the 30lb injectors(ditched the gay FMU) and matching 75mm maf installed tonight.(both used) Let's just say it runs like ass, when it even runs. It's soooooooooo rich. Ordered a holley boost referenced adjustable fuel pressure regulator today($30 used) to hopefully solve that problem. It won't be driveable until it comes in the mail.(hopefully that somewhat solve the problem) What gets me is the "calibrated" maf should be compensating for the change in injectors and sending a modified voltage signal to the eec, but it acts like it's not. Then again, all a calibrated maf does is change the amount of air flowing over the sensors which cools the sensors more or less depending on the sample tube size and sends a sinal to the EEC of how much voltage is required to keep the sensors at a constant temperature. if it is the maf sensor that is fugged up i think i can just swap in my stock maf sensor into the 75mm housing and should work. so i swapped in the stock maf sensor into the 75mm housing and same thing. only two things left it could be is the tune, or the injectors are leaking fuel at all times. so then i checked that injectors are not leaking. i pulled the upper intake and the fuel rail with injectors still attached and turned the ignition to on and there are no drips, dribbles, or sprays. (couldnt do it the easy way cuz my fuel pressure gauge kit is at work)that leaves me with tune or adjusting the fuel pressure....i would have been happier if the maf was bad. lol. but how succesful have you guys been with a larger injector/maf install? did it run like complete ass? mine wont even hardley run unless i hold my foot to the floor and it still barely gets above 450rpms. i just need this thing running to make it to the tuner next week!! if i cant make it to the tuner ill just get a tweecer.......
