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

Opinions are a point of view that is formed by input. Whether the input is fact based will vary, although most people beleive that their opinions are "informed opinions". By that I mean not created out of thin air but based on something(s) credible.

Beliefs are rarely based on facts. It's basically why they are beliefs.


As to the crux of the offensivity.
TTi did advise "don't" which obviously was taken personally. OK. I get it.

RRR did write that the numbers in the mags were not to be relied on, and that was in context of the test that was run by someone TTI knows personally would not "throw" the results. I get it. RRR you probably get it too.

There is a long historical background of magazines writing articles about or that use items relateds to their advertizers. Its not just hot rod mags. The skeptisism is understandable and probably healthy.
I was rather surprised when graphing stock 340 dyno power from two magazine articles written decades apart produced very similar results. Now what happened with the add ons was interesting too. Some of that may have been simply how the engine dyno was run (rate of rpm accel for example) or who knows....
