Possibility of Forge DV failling HELP!!!

[simon_mint_boy]

My Leon Cupra is getting slower.:( Ive got a Forge 007p DV on for a few months but the boost seems to take longer to come in i get max boost at about 2500rpm it used to be 2100rpm. Im only getting 10psi max and 8psi all the way through the rev range.
What could be up could it be the Dv or could it be the N75 valve?
Help please. Cheers simon:saber:

As an early check, see if the DV needs servicing.

Follow this guide from Forge's website.

Remember if its faulty, Forge products carry a guarantee too.

But try that first, then see. To be honest doubtful its the DV though. N75 possibility i suppose, but i have no idea how to fault test it unless you know someone with a VAG COM, or borrow someones N75 to test it on yours.

Sure someone will suggest another probable cause.
