By 954 is running rich and i'd like to try a "leaner" map if anyone has it. All I have is 2bros. Slip-on and PCIII, no other mods. I'd like to go the custom map route, but want to experiment a little more. I know it's NOT the perfect guage for fuel mixture, but my exhuast tip is very dark, only getting 110 - 120 miles before the light comes on and the guys following notice some unburned gas coming from my exhaust, which I noticed on my bud's 929 as well, so i'm guessing that this is common.
