Boost issue

[fire_king]

Hi am having issues with the boost dropping off I had the exhaust system changed from a 2.25 to a skunk2 3" its hitting full boost .5bar but then drops off to .4bar car has been parked for almost a week prior to this it was fine and holding boost at .5bar in all gears.

Any ideas what could be the cause to this? It also got a HKS actuator which is not that old. Also want to add the exhaust has a slight leak after the D/P not sure if this has anything to do with it

Thanks in advance

Boost leak?

Boost leak?

I will check for boost leaks tomorrow. Am just wondering if the leak on the exhaust is the problem causing it

You have free'd up the exhaust so its natural that boost will drop, its like when adding a larger intercooler your boost will drop a little, you simply need a boost controller to raise the boost back up unless it can be adjusted from your wg actuator.
