i have found an s2 rst for sale round my way and its cheap for its conditiom but there is 1 problem. apparently the boost has a flat spot and can sometimes dissapear all together. its been on the dyno and no problems were found and its had new hoses all round so its not a split hose. i have been told that its not the ECU either.

is there anythink else it sould be. if its a cheap problem im gonna move from Wardyxr2 to WardyRST

honestly any help on this would be fantastic as i would love to get this. if there is any moreinfo you might need tell me and i'll find it out
