Looking for help, new tuner with limited experience. I tried to build a base starting tune from the forums and repository but the truck is still reacting odd to any changes. Here are the details:
2001 5.3
706 ported heads, larger intakes
1900 tvs blower-ported case and snout
102mm NW TB
ZL1 lid
Stock CTSV injectors
2 bar MAP
Starting the truck, regardless of ECT, the engine will idle high and erratic. Often hanging around 1700 rpm, if I touch the throttle the RPM's will just hang until I shut if down with the key. Please help me and review the log and tune, I am really struggling why its reacting this way. Timing jumps way up, O2's are erratic. Seems like the MAP is mis-behaving, should I be dropping pressure with a PD supercharger?
