We have been custom tuning GM gas vehicles and Ford diesel trucks with OEM experience since 1995 including all the Powerstroke diesels. We have owned and tested on our own vehicles, from the 7.3L to the all new 6.7L and know what works and what doesn't. Don't settle for the other tuners who claim to know what they are doing but have never owned any of the vehicles that they sell products for. Don't be a tuning tester! Ask before you buy what experience the company has. KEM | |||||||

KEM Now you can get the KEM Performance Special Edition SD card for your 6.7L H&S products that includes ALL of these power levels: KEM Trans only tuning (Level1) Tow1 (Level2) Tow2 (Level3) Fuel Management (Level4) Race (Level5)! KEM Why remove your DOC/DPF and risk getting a fine for tampering with EPA mandated pollution control devices. With our KEM Special Edition Green SD Card, you don't have to! Drive past the roadside testing without worrying, add up to 170 additional RWHP, and stay EPA compliant! Check out our comparison Dyno graphs for stock versus the highest power DPF on tune available on the market. Having power without increased regen frequency gives you the best of both worlds. All the claims of removing the after treatment to get the best fuel economy are put to rest! Now you can have both, highest industry RWHP and legal fuel economy gains. Our F250 race truck has seen over 23 hand calculated MPG (results do vary and are not guaranteed) while still staying emissions legal. (KEM intends to persue E.O. numbers for our Green tuning)
