Not personally, havent had anything i couldnt do myself yet or need a custom tune yet but a few buddies of mine have and a good bit on here. I know wheelstander got his kenne bell tuned there and is running 450+ hp on stock internals that can only take 450 max...had the setup awhile and said still running strong. Must be a good tune
Drive the 3-4 hrs down to kurgan here in braselton ga. One of the best tuners around. Has multiple 800-1000whp cars in his shop and his personal car is a 1200 whp custom 99-04 saleen which last time I was there is actually for sell for around 30-35k. But Bod knows his stuff and would give one hell of a good tune.
