I want thank everyone for their help and valuable opinions concerning my knock under boost problem. With several small constant tuning adjustments the knock has been reduced. Before the WOT adjustment was (4.28) the knock with 8-10 lbs of boost was 5.2 at 789mv. The WOT currently adjusted to...
I purchased the chip, injectors and "bunch" of other bolt on parts from the late Jay Frick in 2012. I do not know any of the specifics about the chip design other than it is a 93 octane Red Armstrong Chip (F3599H), I called Red twice and did not get any useful information.....or customer...

The engine does not smoke, exhaust pipes are gray color inside. The spark plugs show no oil residue. I did add .5 qt after about 1k miles with several hard pulls, 8-10 PDS boost.

That is correct, during the break in period (2500 miles) the engine ran great but I did not test it under boost. I wanted to be careful not to damage the engine.
