There was a slight increase but it was not significant. I took the mileage readings from the last 699.6 miles @ 19.508 gallons before installing the tooter,and the average came out to 35.86 mpg. I didn't count the fillup that had the stock dyno runs in it so that the average wouldn't get dragged down.

Then I took the following 514.0 miles @ 13.133 gallons running with the tooter. Also not counting the fillup that had the the dyno runs, and the average is 39.13 mpg. Not exactly in hypermiler territory.

So even with the peak horsepower and peak torque being essentially the same as the stock manifold, the comparative dyno runs clearly show that the tooter underperformed the stock manifold under wide open throttle conditions. However, it does work very well in normal every day partial throttle driving conditions. When you let out the clutch taking off from a full stop it hardly takes any throttle which is really nice when driving in traffic.
