Did you run a pipe straight from inlet to DV?

Have you got a picture showing what you have done?
Also did you fit resistors in place of SAI and other valves removed?

how many resistors and what OHM etc did you use?
did you also rip the hard lines out?

Mine did exactly the same when I bypassed the N249 valve and I couldnt get to the bottom of it, checked rechecked and checked for vacumm/ boost leaks to which I found none :huh:

How ever after changing my hotside IC pipework from 1.75" to 2.5" it dissapeared and blows off as normal. So I can only assume that I must of 'un disturbed' something when putting the larger pipework in  :laugh:

removed all the pipes when i did it..but as said av fitted all apart from sai pump and egr...sounds mad when chattering but it cant be good for the turbo....my mate did his months ago and his is fine,,,,could just be that some cars like it and some dont
