Thank you all in advance!
I have a 2004 5.3l bored to a 5.7l with the below mods/specs.
-AFR cylinder heads
-42lb fuel injectors -(fuel psi 58)
-FAST / LSX intake manifold
-Jet Throttle body -(#7100)
-Howards Cam -(#197245-12)
-MAF = Stock and the air inlet tube
Does anyone out there have a tune that can be installed to make this run?? HELP Please. I am pulling my hair out trying to get this combination close / right. I'm looking to start over! Everything that I have tried has not worked or has gone in the total wrong direction. I can get it to run but idle stability is very poor. If it idles, when you blip the throttle it will stall coming back to idle.
PLEASE HELP !
