I also had CODE FIX and now truck is not regening...Also it is not resopnsive....I don't believe $3075 is going to be near what we are going to experance in consumer loss$$$$ I have not received settelment yet. Nore have I agreed...we are getting cheated!!!!! I just want what I paid for or my $$$$ back!I am having similar problems after the Aem tune. Getting codes PO299 and PO2459 and now particulate filter is 100% and will not Regen. Dealer is backed up till September 9th. I took the money but now I think some of it will go for a tune once the dealer is done with it. I really wish I knew more about these tunes.
