RC, my experience has been that if you set an engine up on a test stand under ideal conditions without the Cline or IronBay then put the regulator on there will be no change in the way the engine operates no matter what the new conditions are. Also the remote needle would have no effect on it at all.
I find that I have to run my high speed needle about 1 turn out from where it would be without a Cline. And the low speed needle usually ends up about 1/2 turn out from where it was before the Cline installation. It varies from engine too engine and different planes and setups. But thats generally how it works for me.
Could have something to do with thinner air--lower atmospheric pressure-- up here in Denver. Not 100% sure, but thats how it seams to work out with most of the engines I've run with a Cline.
I never had much luck running them on remote needles. But then again, I am severely biased too--I hate remote needles anyway.
