I just got back from another tour and decided to reward myself with a new...new to me B7 S4.

While away i wasn't able to really axcess the net. Ive always read that people made fun of the 4.2 S4 due to lack of performance. Looks like that's changing.

I just had my 06 chipped from JHM and its no joke. The 4.2 chips from what Ive read don't do much but my research on JHM and this video show that they are 100% about the B6/7 performance.

There is a rumor they have a Supercharger for the B6/7. I can't wait to here more as it seems the other offerings with the Superchargers for these cars hasn't performed real well.

So maybe his is a turning point for us 4.2ers..

Nice video I found

So the APR chip made a noticeable difference on your 4.2 S4? That's awesome I saw a JHM video today where they had a supercharger teaser at the end and it sounded like a centrifugal type blower.

 

the vid showed a twin turbocharger setup..

that would be the ****...

The JHM chip made a large difference yes. While I like APR there chip didn't seem to stack up so well. My buddy has a ARP chip and you really can't tell its there.

Ive been reading the results from the Centrifugal blower from JHM and its good stuff. There Facebook page said the JHM Supercharged car went 12.2 @ 119. Not bad.
