I have a 2011 GT500 and want to do the Whipple 2.9. I have the CAI,FRPP Monoblade,it will have 72lb injectors,basically all the needed parts. My question is this. What can or should I go with psi wise or pulley size to run pump gas without any issues? I have been told 3.25 to be safe will be around 18psi still making 650-700rwhp. Im wondering if the 3.0 is too much, I don't want to use boost a pumps if at all possible. Any feedback will be greatly appreciated.
