O.K. i don't understand this one little bit.
My mates asked me if you can increase the boost of the turbo on a 1.9 TDi Astra.
He's tried to do it the "normal" way, but it just cuts out when the boost kicks in. So he assumes it's a vacuum system.
Is it possible?
and if so how?
Do i have a clue what i've just typed...............NO. Hope it makes sense to someone.
