Hi Have Just recently had a boost gauge fitted to my 96 wrx saloon, last week in cooler weather it was boosting 0.9bar now its only 0.8? is it right to think that when the air temp is higher boost pressure goes down? no running faults etc seems fine wouldent have known if no boost gauge fitted.

Cheers mark

 

Thats what the warmer weather does...

 

Yes it will change with air temps.

 

Thanks for the replies chaps.
