Boost controller w/o new computer, negatives?
i am thinking about putting a boost controller on my wrx. it has a stock turbo, but i have an intake which makes the car run a little bit leaner than it normally would and i have a muffler(not exhaust, just muffler).

would it be ok to still but a manual boost controller on it, without changing the computer, as long as i only run around 16 psi? would it make my car run even leaner? and what negatives would there be?

If you have ever datalogged a stock WRX and seen how pig rich it can get, you'd be surprised.

WIth 16psi your fine.

Make sure you have a boost gauge and a catless uppipe installed. Those are a must if your going to be raising the factory boost levels.

no up pipe, but i do have a boost gauge. why is the catless exhaust and uppipe so important. i could see about the uppipe, but wouldn't the back force help keep the torque up?

I didnt say anything about a catless exhaust. Only uppipe.

Raising the boost levels raises EGT's. High EGT's in your factory uppipe can cause the catalytic to fail and blow into the turbo. Not good.

Good luck.

Hey teiva-boy,

Do you have an intake on your WRX? If you say that it runs so rich from the factory, an intake that makes it run a little leaner shouldn't hurt anything right? I'm just looking for some closure on the eternal argument. I figured someone who had datalogged a stock WRX would have a pretty good idea.
Thanks.
