GUARANTEED UNLOCKED, some sellers have sold these programmers after they had been installed on their vehicle which locks the programmer and renders it useless, beware of who you buy these programmers from. I guarantee you will receive an unlocked programmer or I will refund you completely and pay to have the item shipped back.

Im selling my Hypertech Max Energy 52000 programmer, had it for my 1997 ram 1500 5.2L. It definitely gives more throttle response/acceleration. It also gives a small increase in mpg, about .75 MPG for me, this was meant mostly for power. Also gives options to change the top speed limiter and engine rev limit.
It works fine and installs on my truck quick but I just need the money now more than the performance gain. When it came out brand new in was just under $400, now you can get it for about $330 on amazon I believe. Id be willing to sell it quick for $250 shipped, my price is somewhat negotiable, feel free to make an offer.
Please make sure its right for your car before you try to buy it though, its advertised to fit 1997-03 Dodge Truck/SUV 1996-04 Jeep Cherokee 4.0L.

 

Nice pictures. Good luck with the sale.
