well you wont like driving the twins you listed I believe them to be a bit laggy for daily driving towing. my setup I had worked well and made just under 700hp. edge drag comp 62 over 475 I think a 64 over a 480 would work better. fass 150 and some lightning III injectors. the 200's will not put you in the range you want to be in.

 

Oh yeah didn't notice what he wanted to use, great for topend power, not so well for a dd truck

So are the 200s to small or big?? And will the lightnings (a) have enough feul to support nos??(b) and be reasonable as a daily driver???
Who sells the lightning III inj please.

 

If ur gonna be running a 66 over a 480, 200s will be fine but u will smoke ALOT and that setup IS going to be laggy. I regulate my return as well rather than my inlet at about 40psi but again that is on a p pump 24v
