I'm thinking about taking the tpi off my 69 350. How can I keep the 700 r4 and get rid of the computer? This thing will run great one day and the next it runs like crap,idles high one minute and won't idle at all the next,I've set all the sensotrs per painless specs. no power, shifts at different times...etc. this is a 350 hp motor with a stage 2 chip early tpi w/maf sensor.the only thing that isn't right is I still have 19 psi injectors instead of 22psi. I think I have one of them "female" computers that just does whatever it wants to.
