thw weather was very hot like 104 outside. ill get into it in a couple days see what heppens. i just remember making more boost earlier before.

 

Hmmmm...Cog that bitch up!!

 

Is That the same cam as before? If you have any more overlap than before it'll bleed off boost.

 

Surely the hot air is making it feels weak. I know I can really feel the difference when it gets warmer

 

I'd guess that it's many things coming up at once. You are flowing alot more air into through the engine which will drop it considerably. Just a cam alone on a stock engine will drop boost about 2psi. Heat is another thing that doesn't help boost levels. Belt slip might have been a problem, but you would have likely seen alot of belt dust. I'd guess it's mostly just from the heat and rpm level.
