ok heres the deal i have a 91 nad 92 rs 91 is 350 swapped 5spd swapped that runs ok and does not even compare to my 92 rs factory 305 tbi 5spd the 91 is a dog i switched the 350 in complete minus throttle body but i work at a auto wreckers so i will be switching the injectors. here is my question is there a ecm i can simply swap in that will make the 91 have some power my 92 is awesome lots of power but the 91 is running rich pulls good but not as good as the 91.
let me know where to start if the 91 can't be fixed i may sell but don't really want to as everything is new
thanks
luke
