Hi everyone!! I have recently installed an EVC 6 in the car,but could not reached my target boost. My target boost is set on 12psi, so I reset the EVC yesterday and redo all the step follow by the instruction. This time I can reach 12psi and little bit over (13.7). The problem is I gain full boost at 5200-5500 rpm and boost drop afterward. My question is this normal? How to setup the Map correction to let it boost constant till the red line? My car got inter-cooler, full exhaust, basic parts just want to increase little bit of boost!!
