Hypertech Power Programmer III for 1998 Dodge Ram, 5.2L or 5.9L.. Add performance or economy, change rev limiter setting, program for tire size changes (speedometer correction), change top speed limiter, read diagnostic trouble codes. Like new with original box, link cable, and manual. Worked great on my truck, I have gone back to stock settings and tire size and no longer need it. These are $350.00 new from the HiPo catalog stores, Get one good as new for $200.00. P.M. me for contact info.
