I have hit third once on a very long straight into the banking of an oval, where there weren't cones for security reasons (we don't want cars meeting concrete walls). I do hit the rev limiter (7400) in second a couple times in our fast events of the year. I always hit second in the first straight / turns of the course and stay there. Tom's tune and the HFC do help a lot with torque down low on this car, much better than it was stock.
Example of a really fast course :

I think I shortly hit the limiter 3 times on this run...
