Changed gearbox oil. Wasn't too hard a job, certaintly nothing like changing it on the F23 gearbox @bpoin007! Thanks again for bringing your car around to give me the motivation to actually go out and do something haha.
Oil thant came out was aalmost like a melted Cadbury chocolate bar but looked metallicy, 2.4ish liters came out and 2.4ish went back in.
Next step dial up the boost from 17-20psi. :P
