Dennis just called and said the MP-8 is ready for the 6.7 . He said it adds up to 100 rwhp. Seat of the pants power is greatly improved, and the truck drives just like the day you bought it, just with more horsepower. You can call TS directly starting monday and orders will begin shipping friday. its nice to see something available now. no intake or exhaust required, and includes on the fly adjustability.
