Hi,
The EBC is installed and tuned by Unique Auto Sports, it boosts up to around 11psi however it drops further near the redline to around 9 psi. This issue i already gave up on, but another issue that popped up is that on "peak boost" it shows my boost went up to like 12psi, but when i accelerate and look at the gauge it never even goes past 11psi, then the "last boost" shows as 11.4. So i dunno how this happens maybe it spikes as soon as i lift off the throttle? And the peak boost shows like at 12 psi which i was real shocked about, but i never saw this happen on the gauge (EBC gauge as i don't have a proper boost gauge)
I don't know if i explained myself properly so if u didn't understand ill explain it again
