I was told that if you adjust your altimeter in your guage to what ever it directly relates to the fueling it provides the engine? eg if your at 2000ft and you adjust your altimeter to stay on 3000 ft but your actually at 2000ft it will run a bit leaner to think it is actually at 3000ft.. this was a statement fromt the race dept. I am told.. just wondering if im the only onethat has heard this.. I personally don't know if I believe in this because the engine will read altitude from the map sensor and don't really see how the guage numbers can relate to the ecm performance directly, it in my opinion would read directly from the map itself.. anyone??

The altimeter is probably reading density altitude which is what your motor wants to know anyway.

this is true I guess, confirmed it at a couple different places.. its not a big change but sometimes it is the easy way to clean up that minor stumble im told in some sleds with crappy cans on them..

I kinda doubted it to Dwayne. Not sure it makes much difference. But the sheet I sent ya did come directly from Cat.
