question for the 3s guys

[NOT THE BLUE LAMPSHADE]

over a certain elevation with custom performance setups, it doesnt adjust automatically. a normal car (not modified or anything) adjusts proportionally to get the "optimum" 14.7 AFR at any elevation up to 8000 ft, which is where things get hairy for most OBDII systems regarding AFRs. if its running rich already on a tune or whatever you think he has done to it in laramie then it should lean out the lower and lower you go in elevation, since it was tuned at lower elev. it all depends on how the car may have adjusted itself to the elevation it's in now, if it did at all.

jw, who are you getting the stealth from? im in automotive at tech, maybe i know the guy here.
