Title: Random boost dumps?
Post by: cobalt6700 on 25 March 2012, 17:10

Hi guys, having a problem where my car seems to randomly open the dv on slight acceleration, from low down in the revs (1500-2000).

I can see it happening on my guage, hear and feel it (slight jolt)

I thought it may be the n249 playing silly buggers, so I unplugged the vac pipes and bypassed it, yet it still seems to have the problem? I'm a bit stumped on that!

Any ideas?

okay stab in the dark here but could it be the actuator not holding in?

Hmm, well I did a smoke test on it the other day and all seemed fine.

How would I tell if the actuators playing up?
