Ok I am looking at a Paxton novi 2200SL and a magnacharger. I have full exhaust and bolts. I will be adding 4.10s, eaton diff, and a set of SPR stage II's (127550 grind)......So I want 11.50's in the 1/4 mile and a beast mode car. I want to keep the STOCK STB, and that is one of 3 twinscrews that will clear and I am not trying to spend $6,000.00 on this. Which should I get?
