Default Having some fun with a boost controller. (read: fun)

Well, I went out today with my new boost controller to have some fun.

I set it to around 18psi and went on a back straight. The boost just sticks at 18psi and doesn't fall off at all, it was a neat feeling.

I set it at recommended levels for testing, to see if it was much of a difference. as its set right now, there really isn't a point to have it besides the fact that it holds boost a lot longer, so the next question is deciding weather or not I leave it on...


I have it set at the exact level the GIAC chip boosts at... if I were to turn it up to 20psi, or even 19psi, would I hurt the car?

When I had it set at 17psi the first time I hit the gas the EPC light came on and the car went limp. I thought I had messed something up, but boosting at stock levels shouldn't hurt anything.

Default Not sure, it was very odd, I hit it from a stop and it climbed to like 10psi and just went into...

limp...

it was right in the middle of accelerating in first and it was like hitting a wall.

EPC light was on, turned the car off and back on and it was fine...


That's when I came home and posted, I was wondering if this was just a part of doing what I did or if it was something else.

Well, I've read enough on here to know that setting a boost controller to stock levels won't hurt it...

Very weird...


I haven't taken it off yet, but if its going to blow up something, I'll throw the thing in the trash. I was just trying some stuff I read...

Maybe it was a fluke.

setting it lower than the max requested shouldn't blow anything up....

it sounds like you have some other boost issues, and the BM isn't gonna fix that....

Default If things are set correctly, you should NEVER hit a limp mode. Limp mode is there to

protect the engine, and means you have taken things too far, or something is amiss.
