I have an ECS n75, I think I should probably be using stock, as well, I have a big FMIC with silicone but only stock TB hose, and stock inlet hose.

Default OEM. It holds anywhere from 16 to 18 depending on which gear I'm in

I see spikes of 20 to 22

Hmm... I'm only seeing a spike of 18-19. I wonder if its the ECS N75? Or some kind of leak?

Default I had leaks like the Titanic and was spiking 18-19. 22 psi is in 70-75 degree temps, too

it's more around 20-21 when the temp is around 50F. I don't know what to make of that N75, I've never used it. Pressure test the intake to 25 psi. I wasn't happy until I could get 30 into mine without hearing a leak.

Where are the most common leaks?

Default The boost also hunts back and forth by like 2 psi at times during accel. Its weird, hear anything..

about things like that happening? If the boost is hunting or wandering, is it most likely a boost leak? Sounds like it would be to me.

Where is the best place to get info on pressure testing?

Default in the FAQ. The link is at the top of the page. There's a DIY boost leak tester post.

you'll get surging (bouncing boost) if you load up the engine too much. Like if you floor it at 2500RPM in 3rd gear. There isn't really a common place for leaks. Until you pressure test the intake, suspect everything.
