I'm traveling in to Austin and notice my car is running a little lean at 75mph. Indicating 15.8 afr on the wideband. Was hoping to drop my warm CP a couple points before returning to new orleans monday am.
Anyone in austin area got a set of cis gauges i could borrow for an hour or so on fri-sun? Maybe i shouldnt be worried? ![]()

what's it doing on boost ? if it's just there at zero boost I wouldn't worry about it (bet you're getting killer gas mileage huh ? )

yep killer mileage! its a factor of the cold dense air and my speed 80mph. its not "missing", so maybe nothing to worry about...
i turned the idle mixture screw about 1/4 turn cw and my idle afrs went from 12,7 to 11.2. as a result, my cruise afrs went from 15,8 to 15.2...

i think whats happening is i,m getting. .2-bar boot at 80mph and this extra ir (without the extra fuel) is creating a slightly lean condition. At 65mph i,m spot on 14.7afr...
