Lol fair play I'd recommend silicone much better tbh get the N249 bypassed and if that helps if not only other thing I can think of is map sencor :shrug:

sorry to hijack this thread guys but kinda got the same issue, and a bit stumped myself , cra hesitates in 3rd at 3000 rpm then at 4000rpm just change the dv makes a little difference but not much also tried a forge 007p off my mates golf made it feel worst for some reason :s , unplugged maf also no difference , no smoke at all out the back so don't think its the turbo, i'm thinking to change n249 and n75 at the same time , do you guys no how long it might take to do so and where is the n249 actually located ?

N249/N75 valves are just plug out plug in , the n75 is at the top of the TIP going into the Airfilter/Box and the N249 valve is located onto of the rocker cover , if its a lcr take the plastic engine cover off and theres a load of little vacum pipes , its a grey looking box with 1 electric input about 3vacum inputs. ive changed my and still had no luck. My New TIP turned up today so im going to fit that tomorro and try some other Valves *though another mate*
