just to update here - I plugged the power valve entirely and it did not seem to have a lot of effect at low cruise 2K-3K (still in the 12's. above 3K rpm it did seem to get better with a range of 13-14.5 ish. The car drives fine at cruise, there is no issue - just that dam af meter telling me its not ideal. Going to head out to show on long island tomorrow about 30 miles away, so will see how extended driving does without a pv. i suppose the lack of a pv is masking some other issue, but I am inclined to not put it back in but hard to discern if it delivers any power benefit with seat of pants test.
