5.3 tunning questions??
5.3 tunning questions?? I have a 5.3 setup with a 90mm TB and a 218/224 .553/.553 110 cam. After having the motor and setup done to the truck I'm having a hard time to get it to run like it should. Drivability is good until I come to a stop then it really wants to die. Ive tried adjusting the base running idle airflow timing at idle and fueling at idle to no avail. Also when I give it 50%-70% throttle it really runs well. AFR is right at 12.6-12.8 but the second I go WOT then it bogs down super bad reading 9.6AFR so I take fuel out but it still shows that AFR no matter how much I take out. Everything else seems to run well. Daily driving the AFR is bouncing around 13.5-15.1 just on the stop and the WOT is where the issue is. Any thoughts or help would be appreciated.
Thanks
