My dyno printouts are quite different, the precompressor injection effects are striking.
I guess it depends on how much 'over the edge' the compressor is. Well, that's what I thought until I saw further gains with W.I. well inside the compressor's efficient island.

You HAVE to lean the mixture though, or else you lose power (I did that too on the dyno)

Any chance of posting your dyno plot?
