Question Boost Question

This might be a stupid question but : Will warmer weather make the 2.0l boost less? All fall and winter I would hover right above 20 psi on my guage, now that summer is here and it is like 80-100 degrees out, I'm not going over 16.5-17. Any ideas why??

This is all true my friend. Air temperature affects air density. PV=nRT

So I have nothing to worry about? I was starting to think that I broke something. I would hate to tear apart my intake, manifold etc. if the boost loss is normal.

yes its very normal...i'm boosting just under 15lbs with my 2.9 on during the summer.

humidity plays a big part in that as well

Well if you go from 20 to 17 or 16 I wouldn't be so sure that nothing is wrong. I could see like a 1-2 psi of boost drop but not 3-4. To me that just doesn't seem right.
