Thanks fellas, it passed in the end! He was arguing with me for some time about the wheel fitment and was convinced it wasn't a pass but couldn't find anything in the system to fail it under. Got there in the end.
Been driving it a bit the last couple of days and decided I have to do something about the terrible bodge I put in place on the hot side charge pipes. Where I blew a hole in the silicon from the compressor outlet, I cut the bit off with the hole in and added in a cheap piece of ally tube to get me by. However this keeps making a bid for freedom... so I've opted to buy a new 45° outlet pipe, a new straight and 90° piece of ally charge pipe and some connecting silicon in the hopes of having a slightly more permanent fix that doesn't keep leaving me at the side of the road with a screwdriver in hand fixing a rather large boost leak...
Time to enjoy driving it for now while I get money together to sort my bathroom out (moved up the priority list somewhat!), then I will get an exhaust made up, buy some ABS to make some arch liners for and look at making a splitter of sorts. Hopefully nothing else goes wrong before then!
