Default Low boost

Seems like my boost is too low lots of smoke even on 3x3 on edge comp what's the easiest way to find if its leaking somewhere if you look at my sig it should jump to 30 I think easy unless the gauge is wrong or hooked up wrong thanks

You need to check for boost leaks and go from there.

Default Boost

Ok I made a boost leak tester using a small 12v air pump can't get past 6 lbs don't hear anything leaking the rubber boot swells up a little going to run to friends house tomorrow for his bigger compressor I've seen video of people doing it with small pumps maybe I'm doing something wrong? Seems pretty straight foward I even had a bottle of soapy water ready tomorrow's another day

You need to at least get it up to 20 lbs of air.
