The 42DD downpipe is now in. Sounds great and more oomph per the butt dyno.

Default Very cool....here is a tip>>>
the boost machine will need retuning now as the car is running with very little flow resistance...turn off the creep valve completely....you should find the car still feels smooth, and almost like a v6....
From there..you can tune the boost side again...the car will literally shudder if you got the boost machine turned up too much in this configuration..(at least that is my experience)as i believe the k04 requires a bit of back pressure....so just watch the boost numbers...

other than that...enjoy!

Mostly my environmental conscience. But may slip in a test pipe and 110 leaded some day...

Thx, Hans. I now sometimes hit a flat spot when accelerating. Will try BM tweaks.
