Dahlback manifold users..... impressions please?!
Thinking of going that road shortly or EH-ing the stock intake manifold. Curious as to user impressions as I've seen a few people with boost issues that have these installed. Is the ooomp worth the extra cash? I currently run Steve's Stage 3 ModShack Inuction Tuning System (TTDA, Bamm, BM) and am GIAC chipped.

Go EH...or better yet, with all the induction and boost-related mods you have done>>
I'd start opening up the exhaust tract if I were you.
If you do go with an extrude honed intake manifold, the best thing you can do would be to try to get another 5 or so people here to go in on a group buy with you, you can knock 30% off of retail. If you want to do that, contact me for details.

Nope, both my EH manifolds are on>>
Hey Will, didn't recognize the new sig and SN!
I ended up getting my stock 180 manny EH'd. I decided that a FMIC or the dual SMIC setup from a 225 was not in my immediate future, so I upgraded the stock manny.
But if you are doing that, and you need the manifold I still have a nicely-EH'd 225 unit. My brother out in CA has it actually - he was cleaning up the ports for me. I wll get him to finally send it back if you would like to go that route. E-mail me about it if you want.

A flow-bench test showed an average cfm improvement
at each port of about 14%, I think. I have an Excel chart that MoBlueTT did. I believe the VAG-COM users also showed improved flow. Subjectively, I felt like it gained some power, which was most noticeable over 6K rpm.
