whippled Shelby GT350 throwing TB codes

[roc712gl]

Car was throwing codes for high idle, cannot open, cannot close and going into limp mode after throwing them. Got a new throttle body from whipple still doing the same. Got a new throttle body extension harness coming. Any other suggestions would help.

I had some TB codes thrown shortly after the Whipple install, and again after a new TB was sent to me from Whipple. It ended up being the TB extension harness. I've had to change out the harness twice over the passed 3 or 4 years I've had it installed. Very simple fix, but can get frustrating when its occurring. I recommend to not zip-tie the harness to anything if possible, maybe loosely tie to a fixed object but it can't have anything tugging on the cables.

Do you have a third-party tune or a Whipple box tune?

Are you using the Whipple gasket? If so, you can try removing the TB, take out the gasket. When you reinstall the TB, use a very, very light amount of RTV. hand-tighten the screws, let it sit for 15 minutes, then fully tighten the TB. That may help
