VGT actuator install and calibration non OEM tune

[Rawze]

Sounds like a bad/unstable ECM program to me.

Unplugging VGT makes no codes?

Insite no longer knows if engine is running or not?

Can't calibrate turbo?

Back up the ECM image with Caltherm (so that you do not loose it). Then flash it back to its original factory file with Insite. See if those problems go away. If they do then you know what it was.

send me an e-mail copy of the program that is on the ecm for review.

Sound to me like you need to see what hardware changes were made too. Verify things were done correctly.
