a buddie of mine is trying to do a install (smarty jr) on a 07 6.7 cummins. i couldnt help much since i drive a 5.9 and wasnt around for the install. but im tryin to help - so here it is. He is getting a code P0607 which is INTERNAL PERFORMANCE FAILURE (ECM) said he installed twice and i believe was getting kicked off. he said he did install (read the instructions) and the truck turned on but sounded like it was "loping" and had no computer response :confused013:
