Is there any dyno tests that show the power curve difference between an M1 and Hughes intake other than what's on Hughes' website?

A lot of variables to this subject, engine and cam size, usage. our engines [RT] are direct port injected.
Data for your research..

They don't include a single plane in the episode, but they do debunk Marty's bullshit modded keeger and have a couple carbed dual planes which is basically what the Hughes is (plus some drilling for injectors).
For $900 bucks you get 3.5 HP and 9 TQ. Add the $500 throttle body and you get another 7 HP and torque peaks stay the same. They also tested the carbed version of the Performer RPM and a carbed dual plane M1:
That last one there is the carbed Performer RPM versus the best of the modded kegger (with bigger TB). Expect a little less power in EFI form, but probably not an entirely dissimilar curve.

Ported stock intake did make a little more power, but not worth the money in my opinion. The Performer RPM did make good gains with a carb and you would think with the right size TB, it would make similar gains fuel injected, but with better throttle response, idle and drivability. Engine Masters have some pretty good test, I have Motor Trend App.
Pure CFM flow, the M1 2BBL is out in front by ~15CFM, but if the heads don't flow that much then it's useless.

10.5 HP and 10.7TQ isn't worth $1,400 for Marty's snake oil. The Hughes/Edelbrock intake blows his out of the water by a wide margin.
The carb is going to benefit (on the dyno at WOT anyway) from the extra time for fuel atomization as well as the cooling that takes effect versus an EFI mod to the same dual plane manifold. The M1 should see a little more top end at the expense of some low end.

I recall Flying Ryan stating some time ago that with his multiple tests on dynos, the diffeference between the Air Gap and M1 is so negligible, pick whatever is available. I'm thinking there is not much difference from the runners on the Performer vs. the Air Gap
What Nitro states is dead on.
Intake flow means not that much if your heads are lazy.
