"more horsepower is definitely there but i need more time to evaluate it fairly for fuel economy." —Robert P from Freeport, NY bought a Hypertech Max Energy E-CON for a 2003 Chevy Monte Carlo, 3.8L V6.
"Install was simple even for non mechanically inclined individuals such as myself. I noticed the throttle response immediately after installation. I can't attest to the gas savings yet because I can't seem to keep my foot of the pedal and it's winter so you have to warm up the truck before going anywhere. Autoanything had it sitting on my doorstep the next day after ordering it so kudos once again to them for their excellent shipping standards." —Gene C from Rock Island, IL bought an Edge Evolution Programmer for a 2003 Chevy Monte Carlo, 5.3L V8.
