GREAT PRODUCT

Reviewed By jimmy h (Little Rock, AR) Reviewed for a 2012 GMC Yukon XL —11/8/2012 11:00 AM

AFTER INSTALING THE PROGRAM IT HAS RAISED MY FUEL MILAGE UP TO 17-18 IN TOWN AND IT DOES NOT SOUND LIKE YOU ARE DRAG RACEING SOMEONE WHEN YOU TRY TO ACCELARATE IT ONLY SHIFTS DOWN ONE GEAR INSTEAD OF THREE AND TACKING OUT.
