Delta chip in my 99 ford F150

[Supercharged1999]

I recently bought a supercharged ford F150 and found out that it has been chipped with a Diablosport Delta Revolution chip, there is a switch on the dash, but the switch isn't hooked up to the chip, could there be a reason for that? my truck is supercharged by powerdyne, I got the chip, and the switch, I could connect the cable, but I don't know anything about chips, is there something missing?

Tough to say.
Only way to really find out is find the original owner or the person who tuned it.

Thanks

that could probably be bad if he had it tuned b4 he supercharged it, but she seems to be runnin healthy, good tranny temp, oil is level, no knocking, is there any other early signs to take note incase of engine failure? and if I put duals on this truck could that mess the tune up?

Exhaust wont change anything...
