Can u tell me wot boost pressure I should b running on a 2.5 hawkeye sti

As I have put in a boost gauge and it says I am running 1.4 bar

As I know the car is standard apart from 2nd decat. Nur spec cat back and a k and n tyhoon

 

standard boost on hawk sti from subaru are 1.04 bar ( had mapper read mine before i got the map the 1st ever time ). Id suggest yours has already had some form of mapping done to it.
1.4bar should be fine if your car has standard internals

 

I was going to remap it. Wot do I do now

 

get in touch with the previous owner and see what works been done to it

 

Tried that when I first got it. He's moved since then

 

Help

 

Your car has been mapped for air filter K&N Typhoon and other mods,i would drive off the until you are car will be mapped for these mods.

K&N Typhoon are not the best solution for your Subaru..

Best bet if you are visit in your area Rolling road and ask for AFR,Det test and power run and you will see what your car will make and if has been mapped before.
