Ford Recall, Spartan,& Transmission hard shifting
Well I did my 11B23 Recall today, I reloaded the Ford data, went to the dealer, and let them do the re-flash, ( I Just realized today how much a dog this truck was with a stock tune), while there, when the tech was finishing up he ran a scan, as expected there were no codes present, then the check engine light came on, (I have a hollowed out CAT and DPF), when he checked the code, it was for: "exhaust filter back-pressure lower than expected" he then looked at my sooty tips, gave me a funny grin and said all done...
Got back home and spent another 1/2 hour reloading the Spartan tune, and when I ran out to get some dog food, coming back the shifting 2 to 3 I think, was real rough, has anybody else had this problem, or is it a tranny re-learning curve, I noticed when I tuned the first time it was a little rough, then within a week or so it smoothed out, But it did not seem this hard, just wondering...
