at stockish power levels the air intake restriction isn't in the air box or the rf cai is no better than a hacked up stock one. im reserving an opinion until i can get more substantial info.
hopefully the msd intake manifold i ordered 2 weeks ago will show up soon. waiting sucks.

I tried to test my rotofab, heres what I got:
You can ignore the spikes since you have 2 different runs and there is no way to compare airmass at a common RPM unless I can figure out a better way to have excel interpolate between RPM points. It does look like the rotofab is increasing airmass above a certain RPM though.
