    No cats...need tune help?

    Hey all,

    I plan on putting SW headers and a wideband on this weekend (with no cats) to mate with my SW cat back exhaust that I already had installed, and then getting a final tune later. My question is: Does anyone know what I would need to do to the tune to allow me to drive the 2 hours to the dyno so the car doesn't go into "limp mode" since it will sense there are no cats? I plan on driving it 15 minutes home from the shop, then not again until I head to the dyno in a week. I have the HPTuners software, is there any settings to change/upload on there that would do the trick?

    Any help is appreciated

    I don't see why/ how it's going to sense there are no cats

    My atom doesn't have a cat, and did when I bought it, taking the cat of did not matter to the ECU.

    sorry I don't have experience with the CTS but do with cat's / hp tuners (as a customer not a tuner)
