Ahhh! You weren't listening. Benzmac had the answer. The lines to the aneroid only affects power once the rpms are up and the engine goes into boost. If your off the line power is worse than a 190Dc w/auto then you have an ADJUSTMENT problem.
I do not want to steal the glory I'll let Benzmac tell the rest of the story.(vbg)
