On my 2013 Mustanbg GT 5.0L MT82 6 spd, this year at the track is the first time I have noted a immediate power loss on track while on the full main straight at the Utah UMC (formerly Miller) at almost exactly 6000rpm at about 134mph. All other sections of the track it is a normal acceleration to 7000rpm (7200 rev limit) in 3rd and 4th gears. In all 4 sessions on May 06, 2023, the exact same immediate power loss problem occurred at the same 6000rpm and 134mph. NASA TT2 Group
What is going on and what has changed since last year at the track? Two items I changed.......
1. I changed the gearing from a 3:73 Torsen to a 3:55 Torsen.
2. I switched my driving mode selection from 2013 Mustang GT "Sport Mode" (ABS became too intrusive) to AdvanceTrac Off/disabled/ (ESC Stability off/disabled, Traction Contol off/disabled, ABS sytem functional).
3. I have always run my AED Performance Tune in my 2013 Mustang (AED Performance Tune does not disable AdvanceTrac/Traction control. I am looking to revise my tune to AED Track Tune, AdvanceTrac off/Traction Control off.)
Everything else was normal except for immediate power loos at a consistent 6000rpm/134mph on the full main straight at UMC.
Ideas? Suggestions?
