The H23/F22B and the H22 plenums are all identical.
I agree about the Delta Cam thing, but was going to choose the 260, because it is a little better for a street setup, and I am still auto.
With basically an A6 and the H22 plenum, it pulls right into the rev limit (which oddly moved from 6500 to 6700 with the plenum change). I need to get it on a dyno, but I think the power peak now occurs at about 6100-6200 because that it pulls harder up to that point, and then seems to fall off a bit, but still pulls into the rev limit hard.
Another nice trade off to this is that when you shift, it puts you into a better part of the power band, especially on the highway, where there were some definite gaps in the gearing. 3rd is now good to about 105 and then when shifting back to 4th, it puts me at about 4500-4700 instead of 4000, which allows it to pull much better through 4th gear too. I don't know what it would do in a manual, but I am sure it would be better still.
My mileage increase about 3-4MPG City and 4-5MPG highway. Better throttle response, better low end torque, better top end pull, and better MPG with no change in driving habit. All in all
