Ok, had my H reg s2 for about 2 months now, completely stock engine wise.

Decided to put a boost gauge on today to make sure the car was boosting ok. Looking at the gauge, im only getting 5psi boost. Obviously this aint right cause it should be 7-8psi.

It peaks at 6-7psi and then settles at 4-5.....


Ok before i go on.... the boost IS being controlled by a bleed valve as sometime in its life the amal valve has been bypassed.... i imagine because it was faulty.


Ok as im new to the CVH engine, should i control the boost through the bleed valve? just wind it out a bit to reach the desired 8psi? Or does the boost peaking and then droping a few psi indicate a weak actuator?


Thanks for the help.

Ross.
