| TS MP-8/ Rail Pressure Shim Kit
If you don't install the shim kit that comes with the mp-8 will your truck cut out real bad from overfueling, or by throwing an overfuel code? I was just curious before I install my mp-8 b/c my buddy said that if you don't install the shim kit that it will overfuel and start to go into limp mode at about 2,000RPMs. Is this true?
