So haldex service done, and after a day at Jabba it now produces a healthy 250 bhp and 300 ft/lbs of torque. Before the map it was over boosting at around 3.2k then completely dying off, now it gradually increases from when the turbo kicks in and peaks at 5.5 k and holds 250 bhp all the way to redline, very happy!
Plans to release a few more are the n249 delete, simplify PCV with catch can, bigger downpipe and swap my resonated mid section with a non res.
also have a friend who has a Janspeed de-cat, he only wants 10-20 quid for it and I know I'm not likely to see any gains apart from noise, but anyone know of any back pressure related draw backs from fitting a decat?
