ok i am taking my 350 tbi out of my van and putting it in my 1986 camaro z28 with the tpi on the 350 now i know i need to change the knock sensor and the esc but for the 86 do i need to change the prom if i am keeping the 19lb injectors or what do i need to do i can get the 22lb injector but i want to know if i am right that i dont need to change the ecm or the prom please clarify

 

Moving this to the TPI board, I think you'll get better results there.

 

thank you

 

Yes you would need the 22lbs injectors. It would probably run with the 19lbs injectors but you would be maxing them out quite regularly so the 22lbs would be a better fit. Same goes for the prom, it will run with the 19lbs injectors programmed in (probably poorly) but it will be more efficient and have better power with it programmed with 22 lbs injectors. You can reprogram your current chip with the right tools or find somebody locally with the prom burning equipment to make the change for you, or find a factory prom from a 87-88 350 f-body car and go from there.

 

i havent been able to find anyone who does prom progamming
