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 ?
