Howard - glad to hear you made it out there and had a great time! I took the weekend off but will be at the next one. Good work on your times too; I think it took me several events to make that kind of drop!
FWIW Ottos has done a ton of work for me over the last 5 years and I have been extremely satisfied; PLUS the guys are very active in POC and can help with trackside support, car setup, tech inspection, driving instruction, race parts sourcing, and so forth. JW (Otto) has bailed me out several times with spares at the track, as he travels with a van loaded with tools and goodies.
I have a lot of respect for Dave B (TRE) as well, Dave & Tyson have cranked out some sweet projects lately, and Dave is also a POC guy and 914 fan. But I am not sure that they work on 4-cyl cars? A lot of Porsche shops don't...which is actually how I got hooked up with Ottos in the first place. JW and Steve are HUGE 914 fans. JW has been racing 914's since I was 5 years old...which was a LONG time ago

They have a large stash of used parts and can get some surprisingly good deals on new parts too.
Let me know if there is anything I can do to help...as you know I am just a few clicks down the road.
