i'd go a little bit higher, but not much, maybe 5300-5400.
the best way to tell is at the strip, go up with shift points until you slow down, then you'll know
by the way, is this on the factory tach or an aftermarket one? because when my autometer is at 5400, my factory one is about 5800. Just something to think about
