I would suggest you return to your factory tune and see that it performs correctly. What you describe is wrong. Email their tech support. I have asked questions and received answers for eveytime that I have contacted their support.Endemo said:Hello all!
I recently bought a Diablosport Predator for my Mustang 2005 V6
The shifting behaves STRANGE like follows.
During acceleration with full throttle the tranny shifts 1 to 2, acellerates until the RPM hit the redline, then it DOWNSHIFTS - it should UPSHIFT at this point wich leads to revs FAR beyond what i consider safe - just to upshift immediately. This happens at the 3-4 shift also.
I live in germany. Boardcomputer is set to metric values. Was wondering if this could have to do something with this setting?
My wifes car (a GT) shifts at the redline on all the shifts with the Diablo Tune for it.
