thinking about nos on my '02 GT

i have a 02 gt with 48,000 miles.. 4.10 Gears, JLT ram air intake, Pypes o/r x pipe and cat back, SCT custom tune, and new FRPP improved intake manifold.. Will i be safe with say a 75 shot? This is my daily driver i dont wanna do anything stupid and blow it up or something dumb just to go a bit faster. Please give me some input!
 
In general, a 75-shot of N2O -- nitrous oxide ("nos" is a brand name...) -- will be safe as long as you don't have any existing fuel system (pressure or volume) problems.

You might want to think about putting one-range-colder plugs in the car. As well, be careful with your "custom" SCT tune. Tunes for N/A engines typically add a bunch of timing. You actually want to think about taking a degree or two out of a stock tune when shooting N2O (or boosting for that matter) so taking a degree or two out with the SCT tune that's in there now may still leave you dangerously advanced.
 
there is no known fuel problems with the car, so i guess ill check it and make sure though. So with the tune, do i just tell the people who tune my car that im putting a 75 shot on it and they give me a new tune? Bama Custom Tuning sends me mine.

They should definitely know all mods on the car. From a tuning perspective, N2O and forced induction are the most important mods to know about.
