Sounds like a busted pipe to me there's plenty of them around that area. I'd expect a leak or 2 within the first week of a fresh build to be honest. There's alway something that doesn't get put back in its original place and runs through or what ever. Might feel frustrating now but it could be a simple fix.
An ok that sounds better lol. I'd mask up the centres and lacquer the lip again tho other wise they'll go white and powdery. I did a set of 22's on the car a few months ago and he forgot to get them lacquered so I had to do them all again, that was a bitch!
If it was me I'd paint the centres white, can you not get the stickers direct from them? If not try and get one off in one piece and ask josh if he can copy them.
Yeah that's the one, there will be a hard line going to it from under the car as well you'll want to put a uni flow valve on that, there about a fiver off eBay. Yes plug all the ones coming off the TB and it should'nt affect the idle.
Boost solenoid, I cut the plugs off for the air con as well and taped them up. Charcoal canister can go as well and if your willing get an inline fuel filter and get rid of the big ugly one on the firewall.
