Pre-compressor injection: could it induce surge?

[PuntoRex]

Well, I tried dialing down the boost a little, about 1~2psi. And it seemed fine this morning, the previous fluctuation was barely sensible.

The boost taper on high rev range almost inexists by the helps of pre-compressor injection. It was not very noticeable before either, say, maybe 2psi drop near the red. And now I get an almost constant boost from 4000~6000rpm @18-ish ~ 19psi.

I'm not sure it's that the extra 1~2psi of boost made it flucturated. (maybe sort of miss fire) Which I can be sure is now it's running better at this slightly lower boost, equally responsive, barely any slower. It's just my greedy hunger for boost is crying for more :twisted: I guess the poor little engine has already been pushed near the limit at its stock form.

Anyway, I'm happy again :smile:
