[Biturbos4] trip to advanced tuning products (ATP MFG)...

Robby, nice post. It's fun to talk shop with the tuners.

Keep in mind that comparing different cars across different days entails 
different sets of conditions (temps, pressure, humidity, dyno tuning) and so 
you have to take those 180wph v. 211whp numbers with a grain of salt.

My S4 dynoed at 202whp stock (3" exhaust though) and then 260whp with a 
GIAC-x chip (also 3" exhaust). The important thing for me was not the 
absolute number but the gain (roughly 60hp) by going with a chip. This was 
consistent with the chip manufacturer's claims.

I do agree with you, though, that spending all of that money for a modest 
K04 increase seems a little silly when there are so many other better turbos 
out there. Only problem is that very few have been fitted for the S4 because 
of the tight engine bay. Sucks for us. But the S4 is still fun as hell - not 
many cars than can compete in such a well rounded set of areas esp. after
