You know the annoying cruise affect that GM has programmed in so that when you let off the gas the RPMs stay up for about 20 seconds? Can that be programmed out with tuning?

 

Yes, throttle follower / cracker are accessible. Though
baseline air (vacuum) leaks or drilled TB plates can also
aggravate the condition. I don't even notice it on my
car for the most part. It does help save you from stalling
so you don't necessarily want to remove it; just make it
somewhat faster to decay, so long as that doesn't let
you step into yo-yo.

 

No TB drilling and no vacuum leaks that I'm aware of, it runs just like it did brand new...more power though

Yeah, the drivetrain bucking/oscillation is ugly, but that shouldn't be hard to avoid if you use the clutch and throttle correctly. However, for the sake of driveability if the wife drive's it someone else, I guess some throttle follower would be ok. How is it programmed, that is it does not seem fixed, but perhaps is linear??
