hey everyone.

Story goes, yesterday I was driving at about 2pm, and the car said the Outside Temp was about 35c...

I turned to go onto Tonkin and as I put my foot down in first, It felt like it wasn't boosting, the front of the car didnt raise like it would normally, and I didn't feel what I thought is boost.
The same goes for second gear, it just took alot longer, getting to 100 took around 8-10 seconds, which is not right...

Last night, I drove the car again, around 11pm, when it was cooler, and the car was boosting properly again! It felt normal again.

My question is, does the cooler temperature really affect performance this much with a stock turbo? The car is a 2005 WRX 2.0L....

The performance issues happened with the aircon both on and off.

My thought was boost leak at first, but then last night it returned to normal so I cant be sure?
