car is missing

[gary777]

i put some 550cc injectors in my car and im only running 10 psi and its missing during higher rpms im thinking its flooding its self out cause im not pushing enough boost what do u all think i would try more boost but my boost controller is messed up

Are you running an AFC to help control those 550s?

nope not yet and one of my buddys car is having the same problem horsepower house in lexington ky said he needed a afc but if i was to run most boost do u think it would run better

Your running too rich. Upping the boost might help a little bit, but you really need to tune it with an SAFC and a wideband O2. Are you on the stock fuel pump still? I'd get a walbro 190 (if your still stock) and an SAFC and start tunin'!

EDIT just looked at your mod list, I see you have a walbro 255 and an AFPR, you REALLY need to get an SAFC!!!
