Forced Induction and heat
My God!
In Seattle, it never gets VERY hot. (VERY Rarely over 100), and doesn't usually get hot until about late July/Early August, then peters out in late September.
I've noticed for the last few weeks that if it's been over 80 degrees, my car might as well not have a SuperCharger.
Once the night comes in, and it's 65 degrees or cooler, she's back in top form.
But during the day, it's REALLY slow, I may as well not have any mods.
Does heat really make that much of a difference, or am I losing my mind?
I even have a Custom CAI!.

Just be glad you don't live down in New Orleans. It's freaking hot down here almost all the time during the summer. At least 90+ daily. It has cooled down a bit lately because of the rain though.
Heat plays a major part. Since you have a SC, it will affect you even more I think. Maybe you should just take it easy on hot days.

Isnt it amazing how much heat and hunmidy kills the perf. on a FI car? My car gets so heat soaked. The car is awful, i might as well not even drive the car in hot weather. Once the gets cooler, its a whole new story. Also, i had noticed difference in psi during hot days vs cold days. On hot days wi oudl max at about 14.5-15psi. On cooler days i will max out at 16.5psi. It may not seem like a big psi drop to people but believe me, in FI cars, every lbs of boost counts.

Yep.
I noticed today (it was 90 degrees), that I couldn't get over 6PSI.
Just went out to dinner after the sun went down and it had cooled down to about 70.
8 PSI.

I wouldn't complain too much if I was you. You get to fly a freaking jet!
Must be loads of fun. I wish I could at least one day get a ride in one.

There is also something else I noticed with the heat.
In Chicago, it also gets pretty hot. When the engine is cold, I start her up, warm up to about 700 degrees F on the EGT & start driving. The pull is incredible. However, after about an hour or less of driving, the "extra" pull goes away.
ALSO, sometimes, I will have a slight hesitation when accelerating at half throttle or so. It goes away if I go WOT, however, mild acceleration, especially in 4th & 5th gear causes some hesitation.
I take it that it is the freaking heat. Even after I installed the cool wrap on the intake tube (that reflects heat), same thing...
You're not alone iansw.
