E38 - C6 Corvette - Idle issues - TB % will not increase

[Doc]

I looked at the tune file you posted and compared it to a known stock 08 manual vette that I have in my stock cal files. I did the compare feature and first thing the Operating System, Engine Operation, Engine Operation, Engine Diag, System and Speedometer checksums are different. These different checksums might have been what the dealer "updated?"

The stock file was from DropBox.
I never had this cars stock file as it came to me modded.

But good news, I did just drill a 4mm hole in it and I can see that it made a HUGE difference.

I'm thinking the TB was at it's max percentage (24). With the hole in it, it came down to 17% and I can now manage it MUCH better in the tables whereas before it wouldn't listen to me for shit!
