Yesterday I fit a battery box to tidy my engine bay up, mudflaps for winter, APR boost tap, Nomad racing pillar pod and boost gauge.
Went for a spin today to see what boost my car was making don't know if its right or not but APR stage 1 peak boost at 22-23 psi and dropping to 17-18 psi at the redline. My numbers might be a little out as I could only look briefly as I had to keep an eye on the road.
More pics of boost gauge, pillar pod, mudflaps and battery box in my reader ride thread here
