Does anyone have any info on the chip(s) for the NA S4? I've heard hp claims from 300-340 or so for the European version...what kind of performance #s can we expect? Durability on par w/ the 1.0 bar 1.8Ts?

APR does *not* have their dev. S4 yet. It's expected this week

Try MTM, we have been running them in the UK for a while now

Looking over at the Hoppen site, it looks like MTM has (or will have) a 295hp chip upgrade for the US S4. No pricing though.
