Hermine finally hit my area so the next 24 hours are going to be wet. Once the weather clears this weekend I will be installing my AEM WB and collecting all of the pertinent data on the stock intake. Right now my MAF transfer function is calibrated. In other words my curve is 100% correct for my car versus the factory curve that may have had 1 or 2% error in places. I'm going to utilize the calibrated curve as my baseline. After I have that data I will install the Rotofab unit and measure the same set of data. I will show the AFR error introduced (if any) and then show what the calibrated curve will look like for the Rotofab intake vs the calibrated curve for the stock intake.
This approach will eliminate all other variables and get right down to determining what the intake is going to do to your AFR across the range compared to the stock intake. I will do this in the afternoon so there is minimal weather variance to account for.
I don't have an ETA on dyno testing but I will call RPM on Tuesday and see if they can fit me in somewhere in the next week or two.

Awesome! I look forward to seeing the data & analysis from your testing. Thanks for taking the time to do this!
I would really be shocked if there was
not a lot of MAF error with this kit as well as with CAI & Mishimoto units. Not just on the torque curve, but everywhere else on the map. There's a reason GM is offering a tune with this MAF tune corrected to match the hardware.
