I had/have the same problem. I purchased my truck and with in the first week I got the SETC & p0229 code after driving on the highway about an hour. Ive had it in the dealer twice for the issue with no luck so im going to see if i can fix it myself. I cleaned my MAP sensor and EGR tube, i did...
I put the new tune in earlier this week. First impressions is all good. I did have to reset the transmission setting because it was shifting very hard at first, but since I did the reset it just keeps getting better the more I drive.
tune was super easy to install and it’s really nice how easy...
Yea mine has a bad lag especially when i just start it. Im using a pedal commander to help for now but just ordered the GDE tune so hopefully that will correct it.
