just did a l67 swap and uploaded a dhp 1.5 to my pcm ....took it to the muffler shop to exhaust shop to weld 3 inch piping .....all of a sudden car doesn't start windows don't go down nothing to radio and port where you plug in dhp tuner inoperable also nothing to fuel pump....look under dash to bcm and 3 lines to bcm are cut and frayed ...my question is if i buy a new one it says has to be programmed to prevent drive ability issues...is this something dhp can do or am i screwed with dealer only....i am going to cross thread this in tuning as well
