For those of you with a '10+ using a Smarty Jr. What setting are you running for the best mpg. I'm on SW1 timing at default, it drives great but I see better mpg on SW1 w/ stock timing. What's your expierence?

I've only got one fill up with Smarty so far, but running SW1 defaults I got 16.7 city which blew me away. I've been deleted with H&S for the past year and I've only got over 14mpg twice and averaged 13.5.

I've got two tanks on sw1 default timing and I'm getting about 16mpg. I'm goin to adjust my timing on Sunday when I make a 200 mile road trip to see if there's a difference.

According to my in dash meter, it's currently showing 18. on SW1, timing default. It was showing 18.2-18.4 on SW1 timing at stock. I didn't buy the smarty for gobs of power, I just wanted to have an engine the way it should be.
