Simply put gott's mod has taken my mileage from 15.5 average to recently 17.75. Maybe my trip monitor was wrong cause it doesn't seem right at all. Does it hurt my engine, there must be a down side! lol O and this is mixed driving between town, city, and highway.

you can't claim real world gains until you hand calculate it

I gained 2 MPG's from it. I started at 19 highway and am getting 21+ now.

I had nothing else done.

Also hand calculated over 3 250mile round trips.
