Superchips 3714 MAX MicroTuner for 2003 Hemi Ram. Select between "Performance" or "Towing Performance" (91 or greater octane required) or select for optimal performance with just 87 octane. Device enables user to optionally raise or lower the vehicle speed limiter, rpm limiter and make speedometer correction to compensate for tire height changes.
Programmer is in like new condition with step by step instruction manual included. You can change your vehicle settings in about 5 minutes and back to stock settings anytime you wish.
I am selling this because I traded the truck in on another vehicle and no longer need it. I used it to program performance settings into my Hemi Ram. It woke up my Hemi and shifted very precise at optimal times for best acceleration.
I am selling it for $275. I believe they are about $400 new. PM me with any questions. Thanks.

 

I'm interested, did it improve gas mileage at all?

 

Not really any gain on mileage. Never tried to get better fuel economy with it. Just used for performance and calibration.
