The car was working fine til the primary turbo blew, had it replaced with a primary turbo from a b4 and i can get it up to 15 psi if i slowly put my foot down but if i put my foot more than a quarter down on the accelerator the boost just drops to zero instantly and if i keep my foot down the boost jumps up and then drops to zero repeatedly (surges) and i cant feel the second kick in or any kind of vod ??? ??? i understand how troublesome these motors can be but any help would be much appreciated, its a 1998 bg auto.
Cheers
