Hey, I've done a little tuning on some stock Ls motors before. This is my first time for a swap and I have a few questions.

First the motor I'm using is out of an 04 suburban. I want to use a drive by cable instead of drive by wire throttle body. So if I get a 99-2002 pcm and throttle body will it work with the 04 5.3 motor or is there a difference in the teeth on the crank shaft?

Secondly I'll have to turn off the passlock on the pcm. This I've never done before. Where would I find it when workin on the file?

And lastly I did a cam swap while rebuildin the motor, where could I find a how to on retuning for the new cam? Or where would I find tunes already made that I could work from?

I'll post specs on the cam later
