What's A good GTO kit
 

I have A 2004 GTO with a 230@50 I 224@50 E 591/581 lift 113+2 lsa what's a good nitrous kit for this cam? Let me guess none? I plan on switching the cam out maybe this winter for the TSP Magic Stick v.3 ("MS3") Camshaft: 237/242, .603"/.609", 113 LSA I'm also not sure if my 918 comp spings will work though. I was planning on putting in a dry kit and converting it to a wet kit after the cam swap is this possible? Or should I put in the wet kit now? I was trying to not retune the car until I put in the new cam. Do you need to tune for a wet kit? Or a dry kit If I understad right the MAF will compensate for the dry kit am I correct?
