Hi guys, i have a golf mk3 with some mods listed bellow and the car was running very good,now i hybrid the gt18 to 1856 and it doesnt boost more than 1.6bar when it was supposed to spike at 2.3bar but on high rpm it goes to the requested 2bar, if i put the vaccum line directly on the vnt it boosts good...


any help? i already checked changed the n75, and changed the map sensor for a 3bar and is doing the same
