I decided to remove the secondary butterfly valves because once I was looking at them I did not trust them or trust the red threadlocker. My first tank after all of the above was complete, with about 50% city and 50% highway I got 15.8 MPG. It runs the same and I cannot tell a difference in low RPM torque. Before the job I got 18 MPG driving highway only. I'm hoping for an improvement on that figure on the next road trip.
