well i installe the hypertech max energy, pretty happy with it. i went from 28" 70 series to
29" 75 series my truck responded like an econo box no torque or mid range. 10 mins with the
hypertech, i used there premium program (for premium fuel) working ok with 87 oct, set wheel size
to 29" and axle to 3.42, and set firmer and improved shift points. i have better off the line performance
got my mind rage and passing gear back, a firmer gas peddle (no more sponge). and yes popping out
the map screen helps, 2 more mpg and better air flow at highway speeds. in the ny winters i use the stock heat box
and summer i through on my home made cold air filter. think about head over to home depot and get some nice
3 or 4 in rubber plumming pipes and after market cone filter. why pay 300.00 for same thing.

 

mind rage lol MID RANGE, just tired from work lol

 

The hypertech programmer can't give you a firmer gas pedal... Only putting a stronger throttle return spring can do that...
