Thanks to Brian @ Avalon Motorsports home of the best Altitude Tune in Colorado
After reading great reviews from Inferno and caleb on here I decided to have my Stage 3 altituned with Avalon. The car had a couple miss fires fixed along with a few other maintenance stuff and it had previously been tuned for near sea level and 93 oct. I knew I needed to change my tune for a number of reasons so in early Feb I dropped the car off at Avalon Motorsports. The car has been running excellent, after a few questions and concerns I called brian to see if he could look over the car for me and make sure I am running safe. No problem, I drove down there today, we logged the car a few times and he educated me one what each graph means and the logs.
So if you are like me who doesn't know much about tuning or re-mapping your S4 contact avalon. There is a reason some of the fastest S4s in Colorado are tuned there. Brian does great work and his attention to detail and support is excellent. I appreciate the peace of mind and his willingness to double check the car and explain everything to me. Great guy and very professional...
