http://forums.bradbarnett.net/style_images/caliskinv6/spacer.gif Hello all!

I recently bought a Diablosport Predator for my Mustang 2005 V6
automatic.

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?

PLEASE Help!

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.
My wifes car (a GT) shifts at the redline on all the shifts with the Diablo Tune for it.
