Planning on purchasing a charger for my 12 GT car has minor mods, full exhaust, cai, tune and 373s. Shooting for 600rwhp, I prefer centrifugal blowers..whats everyones thoughts on the Paxton Novi 2200, Vortech V3sc, Procharger D1SC. I plan to throw on Boss intake or new MMR mani with 90mm TB and built lower. For now ill be running low boost on stock internals...which has the best kit any concers to either kit?? Also would I be better off getting tuner kit and doing my own injector selection since I have a tuner??
