Heh. Found that out REALLY quick when I tried. that's why I'm playing around with the trans only tune instead I wish we could know the exact specs on Bill's tunes, but that would be bad for PHP's business. I know my truck will never get the mpg of my wife's minivan, but I want to get all I can. The Gryphon was designed as a performance tool, not an economy tool, I get that. But......if Bill were to write a "max mileage" tune I'd definitely be interested.
I guess you can only do so much with a 5000K-plus vehicle pushed by a 5.4l V8. I REALLY like my truck....everywhere but the gas station.

BTW-Is you Tow tune one of Bill's, or stock?
