you have to click on the small image box at the bottom of his post. It will bring it up in another page to view it.

A/F doesn't look too bad seeing that the reading is taken at the exhaust. It should be half a point richer if the reading was pre-cat.

nice solid power did he hook up vaccumm so he can log boost for you? if they did, can you post it

At your altitude you probably need to modify your barometric pressure/fuel trims. Superchargers unlike turbo’s are effected at high altitudes, with a fixed impeller speed the mass flow is lowered due to less dense air, as I am sure you already know. To compensate for this change in density, your EMS has a barometric pressure gauge and this will trim the fuel injectors correctly to adjust. Know that Kraftwork’s has a decent box tune unlike Greddy and some others, I would start by making the global Barometric Pressure Trim then get back into you fueling table and fine tune. In fact if you know what you are doing, you could always start at low altitude and drive into the mountains up to Dillon or Keystone so you have a full range tune.

I would highly recommend taking it to a Professional if you are unfamiliar with this.
