Not too much to update, I've been driving it a lot with no issues.

Forget if I ever posted an engine bay shot after it was running.

The hockey puck mounts caused unbearable NVH, especially above 2500rpms. I'm not sure how I survived 3000 miles down and back to Vegas. I did order some of the orange practice pucks as suggested, but those felt even stiffer so they got returned. Decided to try B5 mounts which I had been thinking of doing years ago. Ordered some B5 RS4 (non-hydrualic) mounts and they work great installed upside down. Might be able to install them rightside up if you ground out enough of the B4 mount, but I couldn't be bothered. Did have to trim some off the thread of the driver's side bottom to prevent it from hitting the subframe, but that was easy. SOOO much better. No more body numbing vibrations at idle and ear bleeding drone at highway speeds. Exhaust still has a small amount of drone between 2-2500 rpm, but not bad.

Modified B4 mount (cut and pried out the OEM hydraulic mount; hole drilled in center):

B5 RS4 mount installed upside down:

Also swapped to all black tails for now:

Clever solution on the engine mounts- did you have those done for the cruise the other day? I should have gone for a ride with you!

Damn! I thought for sure you'd be happier with the orange pucks. The 1.8t is a shaky bastard of an engine though, glad you found a solution you're happy with!

I might have ordered the wrong ones, was hard to tell what's what on Amazon. The ones I got were super heavy and rock hard.

I've apparently been driving with a bad MAF all this time. Was troubleshooting low boost issues and replaced a bunch of stuff (Swapped to 710N, new wastegate, swapped to K03S turbo), but it came around to just being the MAF. New used MAF and it pulls so much better! Probably gained a good 30-40hp.

Glad you got the maf figured out. Its nice to get red of the little nagging issues like that specially when there engine related.
Man I like all your projects and I love the way you infuse the factory look in your cars/engine bays.
