i run a completely standard cupra R and was jus wondering what the turbo should boost to?only hitting 0.5 psi but a few mates are saying it should be at least 1?please help!
 
as i was saying my cupra stock does 0.8 constantly and 1 in boost !
 
depending what N75 valve you have on there, it can spike to 11psi...but standard PSI is 7-9psi
