So, I've gotten these codes a couple of times so far, but only after I put in about 3gal of e85 (not sure what the actual percentage is, waiting on the gas co to get back to me but won't be using it again). 2c7e and 2c6a with 30ff code at 5k
My boost isn't hitting target either, but I haven't checked for leaks/solenoids, etc.
