Hey Everyone,
I need some help....
I installed the Trifecta tune for my 2011 Regal T07 Manual Transmission about a week ago. About 2 days after the tune, while my wife was driving the car, the check engine light came on. I ran the codes when she got home and it said P2261, which is the Turbo Bypass Valve. I cleared the code and hoped that it was just a fluke and wouldn't come on again.
However, a few days later, which was today, the check engine light came back on, this time while I was driving. It's the same P2261 code and now also a P0171 code (Fuel Trim System Lean, Bank 1).
Have any of you heard of this before? I assume it has something to do with the tune. What do you recommend I do?
Also.... I did start using E85 gasoline at the time of the tune. The car has about 15k miles.
Thanks!
