They are one of the premier tuners for Mustangs and F150's with the 5.0. They have years of experience and are very highly regarded in the Mustang performance community. I know they have done 100's of F150's as well. I have their custom tune in my Mustang and would go directly to them if I had the 5.0 in my F150. Give them a call and talk to Jim Jr. He he will answer all you questions and can help you if you only want a new improved performance tune or if you want to go whole hog with a CAI, supercharger and exhaust.
