I have a 2006 Mustang 4.0 V6 and have installed the 93 Octane Program. I have raised the Rev limiter to 6200 and the RPMS are still at factory specs and it still shifts at like 5700. What am I doing wrong here? Also in Park or Neutral it still kicks out the motor at 3700 and I can't rev it up past that. Thanks Sandy

09/14/2014 - After reading a good bit in the forums I put the original program back in the car and then re-installed the 93 Octane tune. It does shift at 6200 now. But if I try to rev it in Park or Neutral it still cuts out at 3700. Any ideas?

Neutral rev limiter is separate from everything else. Post your last tune written.

Couple things. Seems you weren't adjusting the actual shift point of the trans and just the rev limiters. The neutral not moving was because of a torque limiter in neutral which has now been raised and the shifts points set to 6500.

Thank You! Worked Perfect!

I have an 05 Mustang V6 Automatic, and I can't get the shift points to take. Like the other posts here, I'm not concerned about WOT Shifts, like when I floor it. I want the car to shift later in the RPM range while driving normally. However, no matter how many times i update with my U7140, it doesn't work. Any help would he greatly appreciated.
