Looking to purchase a tried and true Tune for my 2009 6.2L Denali. It has 2.5" true dual exhaust and a volant CAI. It's is a daily driver and I am looking for a performance tune...gas mileage isn't a concern. I know people don't really post many tunes on here, but if there is a veteran tuner that has a good performance tune for my truck id gladly buy the file.
Thanks
