Richer as rpm goes up???

[97gsssst]

I was curious I am noticing that when I get on it at about 2k once I am at full boost my o2 volts become richer as rpm goes up is that normal??

Normal. The stock fuel curve is designed to start going richer at the rpms when the stock turbo is spooling up. It then stays flat until 6k or so, then goes richer still.

IIRC, it's trying to do something like 12.5:1 or so until 2500rpms, when it ramps up to 11.5:1 or so, then going to like 10:1 near redline. Something like that anyways, I don't have the fuel curve chart on me right now
