This is from my original post

My ported throttle body has a hole in it and is causing my idle to go high. Ran out of injector before i hit 470.24 RWHP 443.80 RWTQ

Added 80lb injectors flow matched, bbk ssi intake and throttle body(already had from another build). Hotwire kit on main fuel pump and second walbro gss340 activated via boost switch under the hood. I block the factory fuel return and installed a front mount regulator with new return line. Also add MMS crank pulley and 3.2 procharger pulley. fuel pressure and boost gauge

You sould switch your plugs to TR6's and I would also look into running methanol. You will be able to pull more out of her with meth as it will drop IAT's (P1 pullied that much is getting hot) and can add timing. I'd say 630ish
