H6 as you know is a flat torque engine as it is; ideally power/torque figures from 2000rpm up would be the same as stock but with a nice gain north of 6000rpm until redline.
For those runs I needed to start the NA one lower so the comparison is correct, it benefits from kicking off with more rpm on board. We are running more tests in next week or so if I get time, I would say the picture at the bottom end will look more complete
The test setup advantaged the stock intake in terms of testing, it had the benefit of higher rpm start point and lower intake temp but still couldn't match the tuned ram tube for final output and rising torque curve from 4000rpm on. To drive it, I didn't notice a low end loss at all, in fact it was smoother than the stock CAI
Next time I will be sure to try and get the stock intake to pull smoothly enough from lower rpm so I can floor it properly and get it reading from lower rpm to compare more directly
