Turbo and evap
I'm getting ready to boost my lq4, do I need to remove the solenoid from the intake manifold and put a filter after the canister or is it fine to leave it? Heard something about boost pressure on the tank or something

You'll hear a lot of different opinions, my opinion is that for a street truck you can't beat this routing. It's cheap, easy, and you won't smell oil at idle. For an all-out performance build the general opinion is that crankcase mist should not be recirculated back into the motor through the turbo inlet, as it can cause detonation.

I have a gauge for that

The issue with the catch can picture above is you are only drawing vapors out under lower power and not venting pressure anywhere but into the turbo under boost. This is exactly what you don't want. Will be fine for a 500hp build, but more than that I would use a true vented setup.

I'm saying you need to give the air in the crankcase somewhere to go when there is boost present in the intake. Preferably not back into the engine inlet. Straight vented covers work fine but I like running to a vented can to somewhat control the vapors from the breather filter.
