Just got Wheatley to do a 93 street tune this weekend. I had a wait4me tune already, but was very unsatisfied recently at both gas mileage and performance. HUGE difference between the two; it really woke my truck up. Also discovered that wait4me did some messed up things with my tune (like 100% TM removed, shifted into 4th at 100mph instead of at 125+, bad fuel curves, just to name a few). I burned up my clutches because of my wait4me tune; Wheayley said

I picked up 2 mpg on the drive back to College Station to get 18.0mpg, and still need to change plugs and O2 sensors, so hopefully it will go up even more. Huge thanks to Wheatley; great guy and definitely picked up some HP under the curve. Money well spent

 

Please move to GM tuning and diagnostic section. Sorry, I have a short attention span and fudged on where I posted this.

 

Moved.
Street tuning has great advantages over a blind mail order tune.
Enjoy your new found power!
