Long story short- I have an 86 Ranger with the guts of a 14 F150. Did a full drivetrain and harness swap. With that, lots of sensors and whatnot were deleted. I am having an issue revving the transbrake beyond 2500rpm. There appears to be some sort of limiter within the tune that won't allow it to go above that. Truck is tuned with HP Tuners, and have already set the inferred speed to 8k. On the dash, the parking brake and ABS lights are on, as well as the message center for servicing advancetrac. Has anyone dealt with this before and have a work around? My 60 foots are suffering by not being able to take full advantage of my converter.
