Boost Problem Cupra R

[joshyboy300b]

hey evryone, i have a problem with boosting my car.
its behaving realy wierd but will try and explain the best i can.
it dosent happen all the time but sometimes after a hard boost it compleatly dies only hitting 0psi on my boost gauge when trying to accelerate, also whilst doing this the note changes in the exhaust sound to a slightly deeper sound....the only way it cures is by holding the accelorator hard down for a long time until the boost slowly winds up to around 20psi then letting it dump. then all is ok.


i have allready changed a MAF sensor and N75J valve :s
