im a tuning noob so i was just wondering how i would go about doing a catalytic converter and DPF delete tune? also was wondering if there is a way to "unsupport" these items? or make them view as "ready" like from a state OBD2 inspection view point? i know GM are much easier and flexible but i have a 2002 Camaro that is fully built with all emissions crap removed only running 2 of the 4 o2 sensors and when it is hooked up at the inspection station i pass with no issues at all! im wanting to know if i can do this with my Cummins too? oh and my Camaro was tuned with EFI Live.
example of things removed and "tuned out" in my camaro: catalytic converters removed, after cat O2 sensors removed, MAF removed to go speed density, EGR and air system removed i think thats it as far as emissions related items but the car ALWAYS will pass as long as i tip my buddy to ignore that fact that it rolls in on slicks and skinnies and sounds like a drag car!
