I have decided to upgrade programers so I'm selling my hypertech max energy. I had it on my 2001 dodge ram 1500 4x4 but it fits many other applications. Everything that it came with new including the box goes with it. It is unlocked and ready to be installed on a different vehicle. Features of this unit include: Optimized engine tuning for gas and diesel engines, Adjustable top speed limiter and engine rev limiter for some applications, Speedometer and odometer recalibration for non-stock tires and rear end gears for most applications, Automatic transmission shift point and shift firmness adjustments for most applications, Reads and clears diagnostic trouble codes.The model number is 52500.
