Hey, first off I'm stage 2'd with a 2.9 pulley and shorty ram cai and 2.5" catback for the basics. For some reason, Ive lost about 2 psi according to my boost gauge recently. I used to be at 16psi and now Im down around 14. The weather has changed around here, when I saw 16 it was high 20's to mid 30's, and now the low is in the upper 30's. Would this weather change cause a drop in boost? Or do I possibly have a boost leak somewhere? I dont hear anything such as a whistling or any kind of a leaking sound from under the hood. Any ideas, I just noticed this today when I jumped on it. It still pulles hard as hell, just wondering. Thanks!

 

its the weather, the colder it is the more boost u'll see...

 

Alright thanks, I was kind of thinking that.

 

if you had a boost leak there would most likely be a CEL going off since the MAF wouldn't coincide with what your MAP should be reading in the manifold

 

um... you cant leak cfm on a roots style blower.....

 

Alright, Im kind of new to boost since I got this car, didnt know. Thanks to all!

 

Duh!

 

I just went to a 2.9, and my boost jumped to 18psi. One day this past week we hit 70 and I dropped back to 15/16 depending on gear and rpm. I thought something was wrong but the next day we dropped back into the 40's and 50's, I'm right back up around 17.

Don't sweat it, it's the weather.

 

Cool man, thanks!

Ass! Ill see you tomorrow
