Guys, please don't post unfounded mudslinging. Keep this thread about personal experiences with each shop (not heresay) or we'll have to shut this one down. Thanks!

 

Jon@HB Speed gets my vote. Good guy, loves cars, and tunes plenty of them regularly, as well as races/tracks his X competitively. If your willing to come up to Northern California, Bryan@GST Motosports would be another solid option (he currently tunes my car).

 

Go with RRE. I was one of the first to get Ecutek tune from him. He spent over 30+ hours to get it right and for $750. The guy practically lives in his dyno cell. And plus you can go there after work.

My EVO X tuned by Mike (sold while back) laps faster lap times than my stock GTR in Button Willow, Willow Springs, and Auto Club.
