    Help With RPM Limit TQ Source and Throttle Closing

    Good Morning!

    Having issues with my upper rpm, Usually does it around 6,500 RPM where the car will pull hard and then fall on its face. I have only got the car to the 7000 rpm shift on one pull at the track. Car is a Hellcat with a 426cid and 4.2 Kenne Bell with a Built Trans.

    I noticed that right before my TQ Source goes to RPM Limit my TPS starts to drop. Then I lose a lot of communication with my log data such as ST FT, LT FT, Spark, Map, ETC. I attached my Log for reference. If anyone has an ideas on where to start, that would be great haha.
