2015 WRX's built tougher than Ford...

[Alin]

So, the 15 WRX's have a tendency to overboost from what I am seeing... The factory tune has it set for 15.9 peak, but look at some of these....

Interested to see what some tuning will get you from a WRX.....

Crazy stuff.

Holy cow! That's not good.

 

[squrillbait]

Yeah I was a little concerned when I hit 18

 

[HolyCrapItsFast]

Holy cow! That's not good.

Agreed!

 

[squrillbait]

Is this the wrx or the sti?

 

[Alin]

This is only the wrx

 

[squrillbait]

Ohhhhhh well that's better

Happens on the STi too unfortunately, my buddy has hit 22.5 at one point on his 2015... Subaru is aware of this and has said it's not a concern...but they may release an updated base map at some point.

Not a concern? Really?

I would flip out if my sti hit 22 psi

The boost may depend on the load and what gear you are in. Also, as long as timing is conservative during the boost spike, it should be fine. I would be curious if anyone can data log this when it happens and see whats going on. Also curious what the AFRs are when this happens. If its not setting an over boost code, I probably wouldn't stress about it.

Thats the problem. No data yet to show for this.
