I have not checked my pressure with my walbro because I never have needed to. The last time I switched intakes though I had pressure at the rail before removing the rail.

 

For those of you with access hatches or cutouts, how loud is it? I'm sure it depends how well of a job is done, i don't really have anything proper right now to make one but i'm planning on it in the future if it doesn't impare cabin noise too much.

 

Car this morning wouldn't prime. Smacked the pcm a bit and messed with the wire harness and it came to life and ran fine. Problem found. Thanks for all the help!
