Hello, just insatalled a turbodynamics MD445 turbo charger into my 2001 Leon 4x4. Running about 300bhp, but there is a problem. Sometimes I notice that the boost is leaking, it goes up to about 1,5bar, then goes down to 1,2bar before it builds up again. Im running a Forge DV007, could it be that this is the problem, og is it the wastegate?

Any other ideas, no result on vagcom...

Pleas help!

boost truble

It seams like when I give a steady throttle, not floring it, the boost holds. Can it be the DV that is to slow? Or ist it the remap that is no good?

No, dont got any logs for that. Will try to get this during next week. What should I read? Running the N75 J valve, tried to switch back to the original, but no change...
