please, think about my question, too. I rely on your expertise.
questioning my expertise, gasp! 
Well someones gotta stand up to yer - and Pesky is well out of your reach!
I do have a question though TT, how noticable is the lag increase with the S3/twintercooler assembly? I would imagine negligible, as its not an overly substantial increase in volume to the 'charged' system.. but i've never driven one so I'm curious.
Hmmmm . . . TBH, can't say I've noticed any lag at all. That is one of the real benfits of the K03 turbo. Maybe it would be more noticeable on the larger K04s, which are alleged to suffer with a bit of lag anyway.
Thinking about this, I reckon I must have literally doubled by charged volume - as the S3 cooler alone is said to be 30% larger than the stock cooler.
I suppose the fact that the turbo is actually part of the exhaust manifold helps to improve the "responsiveness" of the blower, and as has already been said, it aint the "pressure", but the volume of air which counts for bigger bangs.
I am finding that there seems to be a bigger "push" mid range, and the push goes up to nigh-on the red line too. With just the standard OEM cooler, it would run out of puff near the top end.
I'd still recommend getting both. Though both aint cheap.
