Anyone used there services? I was to late for the last tune date in Ft Worth however they have another coming in April I'm going to make. Looking to get my 09 gmc with 6 speed up to par.

My nephew had his 2009 or 2010 Z71 done (he did the log he sent to them and they sent him a PCM). He said he gained quite a bit of lower end.

They did my 08 5.3. Turned off that v4 fuel management crap and adjusted shift points. Everyday drive ability is much improved.

Yes, Justin tuned my last three GM trucks, highly recommend.
