I installed a Holtzman ATAC unit on my 98 MSRX to take it out to the mountains I was running with a SKI-DUD 583 and two Polaris Dragon 700. I checked the plugs twice and they were a nice tan color, but I Put on 65-70 miles on that day ranging from 4500-7000 ft and only used 4 imp Gallons of fuel!! Sled ran perfect and still runs perfect. Should I be concerned?
 
70 miles using 4 IMPERIAL gallons of gasoline would be 14.5 miles per gallon. That is really good MPG but it's not reason to assume it was running lean IMO. My '98 SRX was always awesome on fuel. The plugs will tell the story, if they're nice and tan you have nothing to worry about. Sleds will use less gas at elevation. Less fuel flow, less power = less fuel used and better MPG. my .02
