Can anyone please help,since fitting my avcr my boost on 1st turbo wont go past 7psi but the 2nd turbo works fine.im not sure what to do to the standard boost solonoid and pre control solonoid as it says to disconnect the boost one and cap the 2 lines but does not say what to do with the pre control solonoid.Any help would be appreciated, Roy.
