i just bought a 2008 f 350 crew with the 6.4. the dealer i bought it from took the dpf/cat delete pipes off for cert. and left the tuner in the console. i want to run the delete pipes for better mpg reasons.. is there anyway to fix the issue? it says "tuner is vin locked. tuner 4 is installed"
can i still use it since "level 4" is installed?
