We at KEM-Performance, Inc. specialize in the custom tuning of Ford and GM vehicles, both gas and diesel powered.

We have been custom tuning GM gas vehicles and Ford diesel trucks with OEM experience since 1995 including the 7.3L, the 6.0L, and the 6.4L Powerstroke diesels. We have owned and tested on our own vehicles, from the 7.3L to the 6.4L 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. Why go elsewhere when you can get the best here!

For more information or to set up an appointment, call 407-319-2026, Monday - Friday from 10AM to 4PM EST (Orlando, Florida) or email us with any questions.

Have a 6.0L with injectors? Has your truck been reflashed and the power and fuel economy dropped? Email us for information on IDM tuning. We don't just put an earlier file in your IDM like some other companies, we do a full custom file to your requirements.

Have a 6.0L and want it tuned but are confused with all the claims from the many tuners out there? Go with the one who has been tuning the 6.0L even before they were publicly available. Email us for more information on custom 6.0L tuning (engine, transmission, and the IDM).

Have a 6.4L and want all out raw pulling or racing power? We have been custom tuning the 6.4L longer than any other company and know how to make safe power! Email us for information on off-road/race tuning for your 6.4L Powerstroke (including transmission tuning).

Have a 6.4L and just want more power and better fuel economy? We have been custom tuning the 6.4L longer than any other company and from our extensive testing have tuning for more power with less regen frequencies to give better fuel economy without exhaust modifications. Email us for more information.
