If you are in the setpoint ballpark with corrections not a big deal, but the log above you much lower, maxing at 0. Log with new tank of gas. I think you just got unlucky with really bad gas. I don't know the Cobb maps well enough to advise.

Hey Josh, sorry, you can tell I'm a real noob when it comes to this correction stuff... Can you please expand on your comment?

I don't get the "in the setpoint ballpark" part.

And when you say I'm maxing at 0, so I should have correction going into the positive, above 0, you mean?

I mean if your timing curve is close to where it should be which you can reference in the tuning file. If you are running OTS pump prob 4ish to 7-10 in the top depending on temp compensation... lets use 4-8. If max is 0 like the one log, gotta reduce the tune aggression. log again after some new tanks of gas. But there's many factors... maybe your gf is a little plump, with her mom in the back going uphill into a 30 knot headwind. can't base everything off 1 log.
