Noticed the past couple of days the fuel pressure gauge is reading 66psi while driving/idle then under load it goes back to 60-62psi. Car has an A&A kit with a BAP which is boost reference based (part of A&A kit).
The pressure has been fine between 58-60 psi until I tried swapping the fuel filter. Long story short tried to swap the filter but it was one of those crappy ones which led to high pressure so swapped the stock one back in. Now even with the stock filter the pressure doesnt seem correct like it was before removing it.
