Diablosport Forums

Hi! I have a 2005 Chevy silverado 1500. It has the high output 5.3. Anyways I have longtube headers and some new exhaust that is going to be put on soon. I have a diablo sport predator tuner that came with the truck. I haven’t gotten a chance to do much research and hook it up to the truck. Does it have a CAT delete mode? One of my buddies did a CAT delete and he said it made his truck run lean because the 02 sensor was giving false readings since the CAT was removed. Any help is appreciated, Thanks in advance.

No, you'd need a custom tune to deal with disabling anything like that.
