    Did you have issues with leaving on P0037&38 and P0057&58?
    If in doubt, multiply everything by 1.1.

    no codes I posted the HP log file, 3 tanks of fuel a long trip and many hits to datalog. It is a work in progress but I believe I covered downstream 02, I turned them off so it should not be looking at the downstream o2 at all. Like I said I could be wrong but there are some earlier in this post that said that is all that needs to be done. I have not looked at my tune but in a few days due to rain but i betting if I left the code it was because the changes I made were so it would not add fuel and set DTC, and so far many drive cycles and no issues.
