I think that it's going to be easier than ever to keep the motor from
knocking. When I was running the JT CIS system, keeping it from knocking was
a bit of an issue. It started running lean around 4500 RPM and the extra
injector didn't have very good distribution. I'm willing to bet it'll be a
lot easier to prevent knock with the tunable fuel curve.
Also, a little less obvious, since there is hardly any restriction on the
turbo inlet side of things, the pressure differential between turbo intake
and boosted air is less, so the turbo should be making less heat, and make
it less prone to knock.
