Hi fellas,
Having an issue with my car and wondering if anyone can diagnose what's going on.
It's a 10R80 and the car has been supercharged for 9 months now (12,000 miles in that time).
Been purely driven on the street with Michelin PS4S and about 8 dyno pulls in total.
Nothing was changed on the car and the issue started about 3 months ago so ruling out tuning issues.
The throttle oscillates once I shift into 7th gear in the lower RPM range, almost like I'm moving my feet up and down on the throttle pedal.
I'm positive I'm giving it constant throttle and verified that from accelerator pedal position in my logs.
Originally noticed it in just 7th gear but I think I'm starting to notice it in 8th as well.
Any idea what's going on?
Included a video, watch for the behavior in 7th
