    Hi I have my Yukon tuned by you guys and I am happy with it. My question is; My mileage has been suffering regardless of driving style and tune/fuel combination. SO I was checking my cats with a IR gun and one has more heat before at the inlet and lower after on the outlet. I know that is backwards.

    SO a couple of questions, I have no code, but wouldn't the tune have indicated a restricted or semi restricted catalytic converter? In any case, I am considering having a "high flow" cat welded in. I have heard some of those will throw a code. Can I have the tune adjusted to compensate for that or have the downstream 02 eliminated. Finally, have you seen any performance improvements by replacing with High flow cats?
    Thanks Dan

    Actually, I have sent a few... I know you are busy, but maybe there is an issue with the mailbox?

    No issue with the mailbox, I just checked and saw that you emailed in, we have just one unanswered email from you. Justin is the only one that can help diagnose your situation. He answers in the order everything is received. He does have a heavy workload right now. We appreciate your patience.

    I sent one email to the "contact us" from your homepage and then I replied to a email thread that originally had the tune info. It isnt urgent, just thought I would I post here to see if perhaps someone else had a similar question or knew the answer.
