Thanks for your input. I was having the same problems in my 94 gs-r. Also, instead of getting different injectors, shouldn't I just stick with the ones the turbonetics kit comes with? Also, I have a IAVC problem. I bought a new one but my car still revs up and down. My mechanic said to replace the computer, or that it was bad, and suggested a P-28 and he is going to chip it for me. So now i have a used p-72 and a used iacv for sell now. Also other parts that I've had replaced with better since my engine rebuild.
