I just installed a new to me greddy ebc. Picked it up 2nd hand so no instructions. I've looked up the manual online & read post after post trying to set it up. Right now I'm set at 50%, gain 20, start boost 35, & warning 60%. That puts me at around 10psi but it alarms & climbs to 12 on my autometer boost gauge. The greddy says max was 10. Can someone point me in the right direction. Car is factory auto turbos, full exhaust, & dual pop.
