Very Happy with Jet Performance Programmer

Reviewed By Mark D (Tinley Park, IL) Reviewed for a 1999 GMC Yukon —6/7/2007 12:42 PM

I gained 3 mpg towing my travel trailer. I also have better performance from my truck. I only wish I was able to adjust the engine settings myself instead of having to use Jet's built in engine settings.
