Have you figured out who you're going to have tune it yet?

it makes troubleshooting easier. So I plan to first use an oversize s/c pulley (or underdrive crank pulley) to keep the s/c boost around 15 psi. That should be low enough so I can still use my existing piggy-back fuel maps and it should work with my existing injectors, albeit at 5bar instead of current 4bar and it should be within the operating range of the S3 MAF. Once that's working I'll be upgrading the injectors, the MAF and probably moving to stand-alone and eventually turning up the boost to 20+ psi.

Wow, cool!!!! Custom one off pistons? Sweet!

that's about the only way to get lower compression in a 2.8

Kris Hansen

Yeah, but I figured that someone already made pistons..

FWIW the glasspack did WONDERS. The sound is perfect. The droning is pretty much gone. I can hear my intake finally ...

They put it right before the axle back for ground clearance and it seems to be working there perfectly.

I had a purple horney on my Corrado, as the only muffler, and it was pretty loud..
