thanks 666DAN, i fixed the problem so now its all back to normal. i also fixed my boost gauge while i was meddling under the bonnet. so i killed two birds with the one stone. thanks heaps.

hey all, i recently bought a '95 R-33 Gtst and the previous owner said that he has a bottlecap wedged in the wastegate or something to increase boost pressure. now, as far as i know the engine and turbo are all factory spec apart from a GFB boost atomic boost controller, it did have a HKS mushroom airfilter that i took off and replaced with the original airbox for legal reasons. when the car revved it sounded like it had an aftermarket BOV (followed by big flutter) when in fact it still has the stock one still installed, he told me that it was just the boost rebounding off the bottlecap hence making the flutter. it still does it with the stock airbox but it's not as loud. i'm assuming this isnt safe for the engine/turbo?? my boost gauge sits on the zero mark and i've been told that it should read below the zero before the turbo spools up into boost. is this correct?? any help greatly appreciated as i'm new to the skyline community.
