since a supercharger and nos basically get more air into the engine you would likely run real rich. The gear changes in chip would likely cause problems with your shift points etc. I dont think it would hurt anything but it likely would not give you any benefit. Mike will im sure shoot you the exact details.

Hi V8,
Well, that would really depend on just exactly what the chip in question really was programmed for, assuming that it's a chip that even has your computer code to begin with.
For example, if it was a supercharger only, then you'd be running pig-rich A/F's & not enough timing trying to run that kind of program on a stock truck, so you'd be way down on power & the mpg would be poor.
If it was programmed for different gears, then your speedometer would be off, as well as the odometer and the shift poings in an automatic transmission. You could also have the top speed limiter kick in way too early.
If the chip was programmed for nitrous, then once again, on a stock truck you'd be running pig-rich A/F's, not enough timing, and be way down on power.
The bottom line is, you *cannot* do that, my friend.
If you come across a bargain on a chip like that, you will have to have it reprogrammed *properly* for your vehicle before you can use it.

Thanks guys, I just wanted to get educated real quick with the facts. I really wouldn't have installed it, and nor would I ever buy a used chip!
Brand spanking new, made for my truck is the way I am gonna go. Mike, with just intake and exhaust, do you do a special program for just those two mods?

Hi V8,
Whether you even need any different tuning depends on just exactly what you do to the intake & exhaust. The typical intake kit & cat-back exhaust system, which is I think what you mean, will be fine. They don't need any tuning compensations beyond what we're already doing, there's enough fuel in the program @ WOT for an open intake & exhaust already.
If you were to do things like change the MAF (mass airflow meter), or headers, then yes, those would require custom tuning to compensate for.
