looking for some guidance, have a 2005 mustang gt with a 4.6 freshly rebuild, all is stock except mutha thumpr cams, BBK 62 mm tb, and K&N intake, car runs great but having an issue with starting, first start have to give the car throttle after that car starts fine, let it sit for 20 minutes and it wont start unless you give it throttle again. I have tried to adjust idle air flow, dashpot airflow, cranking fuel, along with cranking spark, nothing seams to help. attached is the tune, any help would be appreciated, tuned several of theses in the past and never really had any issues like this. also checked the car for vacuum and injector leaks but did not find any
