could any body help with this problem... my car ran 32 psi it needed mapping so i drove it as it was at 32 psi it was a animal!!Today i changed intercooler to a airtech one and fitted the fans on the outside of it ..had a pipe made and fitted that .. now my problem is this.
i turned the boost down to 15psi.. drove it around it was fine and perfect.. i changed the intercooler and pipes and now it boosts to 15psi like the normal BUT it drops back down and holds 10psi .. so i checked pipes they LOOK fine..so i adjusted the boost up to 18psi ... now its hitting the normal 18 BUT dropping down again to 10psi when boosting hard.. im guessing its loosing air somewhere just cant see or tell where .. can it be the bleed valve ? any help appreciated
