CAC testing sorta

I just changed the CAC. I can feel some improvement. However, haven’t seen a sizable increase in fuel mileage. Instead, I hear more turbo sound on the drivers side now. So, my question:

Can I put my tool on the turbo side of the CAC and blow air through to try to find where this turbo sound is coming from on the drivers side? Any negative effects? If it does hold air pressure, what’s the max I can put on it?

I’m still suffering from low fuel economy. With fuel prices jumping, I’m trying to find the issue.

I made the same kit years ago. It did fine at low pressures but if you take the pressure above ~20 psi you run the strong risk of blowing one of the caps out. I did it twice. It's quite dangerous. There just isn't enough friction to keep it in the CAC boot no matter how tight the clamp is.
