I can feel the difference in towing our 36' camper. Haven't tried the performance setting.

Fairly easy install for a mild mechanic. Love the fact you can see what temps your car is running at. About a 1.5 mpg gain if you dont stomp on it, definitely can feel a difference when you do though( and thats only on regular setting, i havent tried premium setting yet. Not sure why the 50 state legal one is $100 more...but thats besides the point. Installed on an 06 silverado 1500 5.3L.

the hyperpac fixed my odomoter, speedometer, tachometer, and transmission due to my aftermarket 22 inch chrome wheels wrapped around toyo proxes. i bought the hyperpac becuase i had my check engine light on after i installed a throttle body spacer under the hood. the diagnostics section doesn't quite solve problems but only tells you the code and leaves you to figure the rest out. my diagnostic trouble code reads "System too lean (Bank 2)." i'm hoping that it is just a leak in the air flow and it doesn't have to do with the actual air/fuel ratio. i am gonna disect my intake today and hopefully solve the problem. other than that, the hyperpac works like a champ. i need to construct my center console so i can mount the pac in a logical and efficient place.
