    First of all I am very new at this so don't everyone yell at once!
    I am sure this issue has been dealt with a million times but here it goes
    I have the larger dual exhaust with no Cat converter anymore
    both O2 sensors are still in place however.
    I need a tuner or someone who can do the program that will take care of this...

    Any real shop that does dyno tunes will turn off the sensors that are not needed with a catless exhaust system. Im not sure if any of the shops you send your stock computer to can do this, my only experience is taking my truck to a shop for this.

    Thanks for the input!
    So you know of no tuners I could buy that would do this??
    I'll be looking for a shop that's reachable from my place.
    Thanks again

    ive never looked that deep into them but like i said with what you would spend on a dyno tune the flash tune kits are not worth it unless you have a diesel
