Welcome! The car looks nice, and I hope you get the issues resolved soon. From what it sounds like, you have larger than stock injectors and nothing to control them with so they're dumping in way too much fuel, since the ecu thinks they're 450cc injectors. Another thing I see in your pics, is that your BOV is venting to atmosphere. Which means that as soon as the bov opens, it's like you have a huge boost leak, and all that metered air leaves the system, resulting in too much fuel entering the engine.
