noticed that my 7 doesnt run as nice on a hot day as it does on a nice cool night...yes i know "cold dense air is a lot better" but it feels as if i drop about 30 horsepower during a summer day compared to a summer night...is everyone's 7 as tempermental as mine??

 

Mine definately is, I'm still having some sort of secondary boost problem on my FD...but it's weird...if it's cool outside both turbos work perfect...on a hot day...forget about it. 5 psi max out of the secondary.

 

i dunno, if its over 50 where the cold start doesnt engage it runs like a bat outta hell..........but above 80 or so it sucks
