We have been custom tuning GM gas vehicles and Ford gas and diesel trucks and cars 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, supercharged Mustangs, and all F150s including the new F150 EcoBoost. We 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. We also offer export tuning for vehicles (including the heavy duty trucks - with Cummins and Navistar engines) going to other parts of the world with different fuel requirements - call for more details. Competition tuning and products are available for the true racer, call for details.

KEM 6.7L Turbo Upgrade Kit for 2011 to 2014 F250 to F550 Powerstroke trucks.

KEM is proud to introduce our 6.7L Powerstroke turbo upgrade kit!  This kit contains everything needed to upgrade the turbo on your 2011-2014 F250 to F550*.  Our kits are the only ones on the market that are engineered to be 100% DPF friendly and street legal, requiring NO EMISSION PARTS REMOVAL.  It is available in both Borg Warner 63mm and 66mm sizes with or without an optional wastegate from TurboSmart.  Along with the added power from the turbo upgrade, our test vehicles have even seen an increase in fuel economy but as all driving styles and trucks vary, fuel economy increases are not guaranteed. This kit contains a non-VGT turbo, so it will require custom tuning - tuners in stock and available to add to your orders. Why risk removing all your emissions equipment to get a more reliable, durable, and powerful truck?  With KEM, you don't have to!




Call or email us with questions and/or to be put on the waiting list.

 

Introductory price: $3799 (wastegate and tuner additional)

 

*Different parts are required for Cab/Chassis trucks -  Please note this when ordering.
