Thanks for the heads up about the O2 sensors. I've had this truck for several years now, and was getting 18-21 mpg consistently from it. I've dyno'd the jet chip as well as stock and performance tunes on the truck, the a/f is fine w/ the chip and although the gains are small and only in the higher rpms, they are there.
