i had a 50 mile drive of it with just Dump valve, and difference was noticable!!
Nah boost aint raised THAT much!! its only 5 psi more than std! The D8A system will take 22PSi comfortably.

Of a petrol engine when you come off the throttle the butterfly valve closes and the air has no-where to go exept through the dump valve. Withoput this the pressure between the turbo and throttle is gonna build up and therefore slow down the turbo.
On a Diesel there is no butterfly and the engine constantly sucks in air. This is why you can't fit a DV to a Diesel that will improve the cars performance.
That make sense or do you need a picture?
