TAG Mileage
I've had my TAG installed for several weeks and immediately noticed the engine ran smoother and spool up was better. My truck seems to hold cruise speed with less effort than it used to.
On Winter fuel, I consistantly average 16. 5 mpg. The last four tanks calculated at 16. 4 to 16. 5 mpg. After installing the TAG, the next fill up calculated at 18. 2 mpg. The best mileage I have ever gotten (19. 7 mpg) was when I "babied" my truck thru a whole tank of fuel, just to see what I could get. You would go insane driving one of these trucks like I did and it really takes all the fun out of driving one.
I am skeptical about this number, which is the reason I've held back from posting this, but it's what the calculator came up. Before I am absolutely convinced that the TAG actually made this difference, I want to see if the results are repeatable. I use my truck to commute back and forth to town and have made absolutely no other changes, other than installing the TAG. Driving conditions were the same before and after the install.
Does it help? Yup, I think it does.

Second tank of fuel calculated 18. 7 mpg on Winter fuel. Looks like almost 2 mpg better economy with the TAG installed. A friend who purchased one an made a trip to Las Vegas last week called me when he returned and said his fuel economy was up by almost 2 mpg.
