What about the catalytic converter? If it gets very hot then
it could be clogged, causing the loss of power.

and that's why I have not gotten a programmer for my truck. I have heard about so many bad stories with programmers/tuners/chips, UNLESS it's like a new vehicle.

Changed the wireing harnes and the ECM and had my keys repro and the truck wont start,,,,,,,,,now what,,,,,,,,,,

since i'm only one helping....get rid of programmer/tuner, look up threads on not starting because of SECURITY SYSTEM, pretty sure that's your problem now, security system not letting you start it. almost sure its your security system not allowing it to start, good luck dude

I can put the old comp back on and program the key and it will run,,,,,but not with the new comp on it,,,,,,,
