Ok, so after copying the following tables over from the GTO tune, the truck runs pretty decent, but the idle isn't perfect. For those with upgraded injectors, what tables did you modify? care to share your tune?
flowrate vs kpa
offsets vs volts vs VAC
Short Pulse Limit 3.997
Short pulse adder AND Minimum In Pulse HAS NOT been changed since the Rows are labeled differently and I don't know how to copy paste these without jacking it up
And the default injector pulse field doesn't even exist in the GTO tune.

Setting the desired idle RPM and then adjusting your idle airflow by doing a RAFIG and RAFPN should help. Depending on the cam, additional timing in your base, low, and high octane (low RPM/low load) tables may help.

The cam has been in the truck for at least a year. The tune was adjusted for it long ago, been perfect until the intake and injector swap.
I dont know exactly what is wrong with the idle, but sometimes it shakes a bit, runs rough, and thefuel trims are -/+13...
