If you spend a lot of time with the throttle all the way down (:heh:) how about a URD MAF recalibrator to lean down the air/fuel ratio at heavy throttle.

Mash the gas pedal? Moi?
Rarely, does the pedal meet the floor.
Most of my driving, at any speed, is gently getting to and staying at 2,000 RPM. And I use cruise from 25 MPH, even making minor adjustments of speed with the cruise control.
Leaning the mixture at crusing speed is what I want to do.

None do. Only possibility is the unichip and have it tuned on a dyno, but so far no one has posted credible air/fuel values on these trucks with their unichip install.
