Product Description

Our performance tuning for the 4.2L I6 typically yields 10-14hp and 1-3mpg, as well as better throttle response, driveability, and more pep off the line. Our tuning also helps with towing if you choose to do so. We can account for most modifications you might have (2002-2005 year models: we are not able to make speedometer corrections or remove park/neutral rev limiter). After placing your order, please fill out an order sheet for your vehicle (here). What program should I use and what is refundable? Click here! Express shipping only covers one shipment for loaner programs, the second will be returned via UPS Ground unless other arrangements are made.

    Got this tune for my wife’s rainier. The power and shifting improvements are remarkable! It’s also getting 2 to 3 mpgs better than it used to! Thanks guys!
