I have the same set up - the n20....I trap 122 mph n/a.....I leave off the limiter 7200 and the car dead hooks, bogs and then comes back....You have the right gear...

Raise your limiter and set your shift light.....I'm shifting at 6800......I'm going to 4.56's this weekend.....When I decide to spray, I'll drop to 4.30's..

IMO, I think you should keep the gears you are currently running...
