i have 1994 chevy truck that has pcm 16196395 and a manuel trans it used to have a 4.3 v6 but that is long gone. it now has a 5.7 that up till now had a holley projection on it but i want to remove that and put a factory TBI on it. i am having trouble finding 5.7 with 5 speed manuel bin files to use. i am new to programing a gm fuel injection so any info you can give would be much appreciated. i learned the holley units but they are quite a bit differant .i have the moates autoprom and tunerpro but there is so much there i dont know where to start.
