The guys here will not lead you wrong. I started off barely making 32 mpg combined and with some software re-programming (to my brain) I was up to 36. I added a grill block and was verifying the benefits when I got ants in my pants and upped my tire pressure from the 44 psi sidewall max F/R to 48F/44R and yielded my first tank above 40 mpg. I then upped all tires to 50 psi and had two more tanks in a row over 40.

Had my best trip yesterday of 125 miles of combined mileage and was showing 43.6 on the UG.

Trust them when they say those silly devices don't work!
