I'm in the Denver area (Boulder to be exact) and need to find somebody that is competent in tuning the 2.5L engines. What shops around here have AWD dynos? I am currently running a Vishnu turbo back exhaust and XEDE. I'm not thrilled with the XEDE but it is what I have for now. My problem is the CEL is being thrown ever since I have moved up here to altitude. It never did it at sea-level. I've had the problem for a while but have been lazy about dealing with it. FWIW, the codes thrown are misfires on all cylinders. I can't physically feel notice any ill effect or hear pinging or anything.

Anyway, help is appreciated.

thanks!

Hi Josh,

What modifications have you done to your car. We recently finished a dyno tuning trip up to Colorado and we have quite a few maps available for high elevation. Take a look and see if anything is similiar.

I recommend you contact Tarmac USA (303.442.6508x2) who happen to be in Boulder. IMO they do great work, and seem to know your engine. They also have a 4wd dyno.
