Tunercat Tune Review?

[dave w]

Hi, I figured out my problem with my 0411 PCM swap and i am now required to pump the throttle during start up in order to get it to fire and have to feather the throttle for a few seconds in order for the idle speed to stabilize. It is also pulling ~12% fuel, but i imagine thats not a huge issue due to the adaptive learning. I know its a tuning issue because on the black box the engine would operate perfectly. Engine was fully rebuilt by me and has the following:
gen vi 454 bored .030"
heads milled .010"
Intake valves back cut
Comp cam: .510 lift, 212/218 duration @ .050, 113 LSA
fuel injectors are 0280155715 EV6 rated at 24lbs at 3 bar (my system is running 4 bar)
EGR removed

Would someone be willing to look at the tune file for me and see what they see? Maybe make recommendations on what to adjust? Thanks.

Attached is a Stock 2002 Express Van 5.7 liter with 4L80E .cal file.
Also attached is the "Compare" summary .txt file.

The Express Van will have a different gear ratio and tire size, so the transmission shift parameters will be very different.

I wonder if the attached 5.7 flash, which has VATS Disabled, is worth trying? Sometimes, tuning requires starting from a different baseline flash. I've sometimes had to start all over, with a different flash and make "baby steps" to get a good tune. I often make only one change at a time, to verify if the "one" change is good or not.
