Been working on this for a bit now. 03 Sierra 4.8 swapped to 5.3. 10.0 to 1 CR,222/
[email protected] 112LSA,TrailblazerSS intake and injectors,
LS3 90mm Throttle body using XLINK adapter, return style fuel system (no vac ref) p59 pcm.
Running better but still a few starting and idle issues Below are attached tune files, Initial read before any changes
Current read AUG 18 Pretty sure all the basic parameters are right for the 5.3
3 log files AUG 18 Runs pretty good going down the road but tends to almost stall when throttle released
Have changed base idle airflow and base rpm. Have made changes to throttle follower and cracker
Was starting good but something has changed not sure what
Have made small changes to MAF calibration
Still new to HP tuners so any advice is appreciated Thanks
