I live in germany. Boardcomputer is set to metric values. Was wondering if this could have to do something with this setting?
PLEASE Help!
Endemo | 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.
