My car has been boosting regularly at 10 psi but i have noticed that if i give it some stick its boosting as usual after when i drop down to regular speeds and rev's it wont go over 5 psi? then when i turn the car off it returns to normal until i boot it again, i have Vagcom'd it but nothing showing. the car appears normal except the boost, it is only recently i have noticed this, or it has started tod o it, the cars not heavily modded just 007p Dv (on the wrong way round), neuspeed air filter and LCR twin intercooler conversion all of which have been on for a long time. the only fault that is showing is the usual pressure drop between manifold and Dv ( check DV ), i know a lot of people get this fault i have checked all the pipes and the DV but found nothing.
I Would appreciate any ideas as to what MIGHT be causing this.
