Just got a fmic and now the boost has dropped to .4 bar. I was expecting a drop but it seems a lot to me.
Do I have a boost leak or is that drop normal??
Have you got the hose that runs from the factory boost solenoid to the intake side plumbed in right. If you do check that you have the restrictor from the stock hose and ram it down the new silicon hose. It wont boost properly with out that in with the factory controller. Also check you BOV isn't leaking(opening).
Ya over fueling but was like that before I fitted the intercooler.
Had a good look again today and I found a small leak, fixed it but only got about .05 extra.
I'm thinking now that it's just the size of the intercooler.
Thinking of getting a boost controller to get the boost back up.
