We did stay at WOT for a few minutes and no speed increase.

I think something is still holding the engine back. The total timing thing could be that, or you have some restriction in the fuel delivery.
OEM says 1.50 to 1, I'm assuming current drive is the same. Forgive my noob-ness, how do I confirm drive ratio, and once I do what simple calc?
Thanks for any edd-u-mah-k-shun you send my way!
