hey guys, i just got my hands on a attesa u13. the previous owner had the boost control set to 15psi, as far as i can tell its a standard ecu and injectors.. wouldnt 15psi be abit much for it... considering it has a t25 on it ive turned it back down to 12psi. but as the title states, i was wondering if they have a factory boost cut.. any info would be very helpfull.
