UpRev Tune Questions...

Also, Jack Cecil, the tuner, raised our redline to 7900 and the car was pulling strong all the way to 7900 which was surprising.

Afaik, only GTM is working on cracking the VVEL control, not sure how that would "mesh" with an UpRev tune but I'd guess you'd need both. Custom dyno retunes at HP Logic are only $195 so it's not a big deal to come back and do it again as I add mods (I'm also on the fence about the M370).



In a word, yes. You have to consider it this way and just hope that whatever dealer you go to is nice. Their consult III will be able to tell that your ECU has been flashed, even if you are running the stock map iirc.
