I bought obd2 Bluetooth tool and download dashcommand. I check several times and different days 4th gear 2000RPM till 6000RPM. The result is max boost 24.1 psi. According car spec max. boost must be 22psi. I am living at 3600 feet altitude. What is wrong? Reason is altitude or something different. My mods are EC phase 1, DV+, EC V4 and GWR muffler.
