I am relatively new to working on cars and applying mods, as well as forums. I have an 07 grand prix Gxp. I have put a magnaflow catback exhaust, k&n cold air intake, 90 amp alternator, yellow top optima battery, Bosch Iridium platinum fusion spark plugs 4509, msd super conductor wires on my car. I have a sound system, advanced million color led kit underbody, inside, and fender well kit, and lots of Hids which is why I got the alternator and battery. I have diablo trinity, which I am not sure how to use or tune as well. I am trying to mod my car for performance as much as I can, but i need help and advice. I have read about headers, cam, rockers, tuning, maf, tranny cooler, among many other things. I was wanting more info on doing these mods and others and what i should do for best performance and the order I should do them in, because it will not be done all at once. Also, advice on spark plugs, I was told to use the NGK 61X, but online it says they are not for my car. I haven't had any problems out of the Bosch plugs mentioned earlier though.
Thanks
