Ken, Got the e85 sensor issue figured out. It was an output issue in the sensor itself. You mentioned possible vacuum leak causing the boost control issues, during the major repairs I replaced all of the vacuum tubing to the canisters and solenoids. On Tuesday, I will be changing out the canisters to aluminum replacements from Vargas (not because of any leaks that I am aware of, just for looks) so either way they will be new. The solenoids are the original units, fyi. Thank you.
