Joe Gibbs package

[splatrd]

I found a Joe gibbs performance edition truck wrecked. This truck is equipped with 5.3 L and a supercharger. I am hoping to transplant the engine into my 1972 C-10 truck. What I am curious about has to do with wiring and programming. I would want to buy or modify harness to be stand alone and eliminate extra crap like emissions and VATS. From what I understand, these trucks had a SuperChips tune. Does anyone know if the computer can be re-flashed to eliminate certain functions, but still keep performance tune? Mainly because I don't want to lose the tune related to the Supercharger function.

I have not been able to find any information about what Joe Gibbs did to the fuel system. I am curious if the tune was adequate or if they had to change injectors and/or fuel pump?

Thanks for any help on this.
