i have an 07' z71 with the 5.3L and installed the max energy, to me its like night and day compared to factory, every now and again i'll remove the program and make a test run to remember factory power levels..mileage too, increased 2 mpg w/ max energy.. 4-hi+tow mode= redlight racin monster
IT made the exact same TQ numbers with the programmer. Everyone with a truck knows that you want your TQ numbers @ lower RPM's. Over hyped!

@308scoutfl... You must have a six cylinder vehicle because this works great on my V8. The programmer isn't gonna work miracles either.
