When do I stop accelerating!!! (Where's my redline)

I have a TSR built 2.0 8v with big valve head, lightened flywheel, balanced parts etc tuned to 160bhp with a 50 bhp shot of nos.

Its running like a dream but I'm worried about over revving/not using all the power.
I have a dyno print out showing the power curve and I've just fitted a larger rev counter with shift light which I'd like to set at a safe rev limit whilst using the new power from the engine, should I shift at/after/before peak power is achieved?
Maybe i should just feel for the power dropping off, maybe I'm thinking about it too much…… Maybe YOU can help!?

Post up the dyno print out & I'm sure someone can help from there

yup shift before the power evens or drops, where its most fun, its going to be up around 6000 i'd guess, its only a guess though based on my 150bhp KR, i prefer to shift at 5500 though, dont know why just feels and sounds right….

the dyno print will help a lot as all engines are different!

"When do I stop accelerating!!! (Where's my redline)"  

Answer:
When you see the DEVIL!  

Used to work for me.   
Don't start me on braking points.

Just a bit fun because my engine is untouched and I only push it to 3,500rpm now and again to give it a bit of a clean out but good luck.
I'm sure someone will have the right answer for you mate.
