Angel Tuning did a re-map for me, and installed a CDA. I've since installed a KAT back replacement too. I haven't put it on a rolling road but I did notice the improved torque. My wife described it as the car having had a cold before and it now being cured.
I know this isn't really scientific as I haven't put it on a rolling road, but I think the original question was about options, so there's one!
The point about the cheap pipes is a good one as the air at the edges will be going slower anyway.
The other point of course is to make sure your picking up cold air!
One more thing, when I had the CDA fitted we chucked out loads of excess pipes and plastic molding so I got a weight saving too Seriously, has anyone found a way to save weight? The only big difference I noticed was changing the exhaust.
Cheers,
Matt.
