Port my current M1 single plane or install the RPM Air Gap?

I'd have to see it for myself. Engine Masters is a joke like all the other magazines and tv shows. Whoever their biggest paid sponsor is they sway to. I don't trust anything.
yes they probably mess with the dyno numbers .
I'd purt near bank on it.
I suggest doing a little research before claiming they alter dyno numbers for a (magazine) tv show. I’m lucky to know Steve Brule and had engines dynod at westech and can tell you first hand he is one of the most honest people I’ve met. Making a statement like above is fine if you have proof. If not, don’t.
