In that configuration you shouldn't be hitting the rev limiter until 3,200 - 3,300 rpm.
If you want to go higher, you can request the Smarty TNT-R tune from Bob Wagner. The Smarty is something that will stack well with your existing TST/EZ combo. However, you're going to need the necessary mods to support that, including valvesprings, fluidampr, etc. In addition, it'd be smart to also pin the balancer and go with an aftermarket cam. Water injection would also be wise, and you need to address the rear freeze plug issue as well.
