I have a 20 camaro with a hhp tcm. I'm having an issue, when just using the paddles it seems to slip the transmission. When having the vehicle in drive the vehicle is fine. Anyone have any idea what can be adjusted in the tune to fix this issue or could anyone look at the tune? . Thanks.

Look for the TUTD areas. You may want to provide tune & log files. 😉
Is this an HHP unlocked tcm? But agreed, tune and logs would be great.
this is my current tune , i will have to log the issue, seems now when the vehicle is in drive its having issues. most of the time when slowing down during normal driving ,making a turn then getting back on the throttle.it seems to slip then grab. But when you give it more throttle when its having this issue it does not seem to upshift and make the trans vibrate.
might see the issue when it shifts from 2nd - 3rd in this log , but will get a better log
