quick ques., if a gn has 20 psi boost @ 50 degrees air temp (winter),... @ 90 degrees air temp. will the boost still be the same with no changes mechanically? in other words in summer will boost drop because of hot humid air? when i got my car in december i would see 20#. have since added a power plate and alky, and now see about 18#. have adjusted wastegate about 3 rounds and am seeing about 19#, but here in arkansas (now) it is 90 deg,. and very humid.
