i took my car to j shop who fitted the ebc n found out my stock bov wasnt blocked off we he blocked it off n drove set the ebc to low boost which was .4 however still overboosted to .9 bar he fiddled around with tubing and bypassing sumthing until we got it right so now my high boost is set to .7 bar which worked it hits that and doesnt go further however after this i hav experienced more problems it wont hold .7 bar any further then 4500 rpm at 4500 rpm at .7 bar boost it will just release with my foot on the pedal, so now i hav another problem
