I'm experiencing two problems. Please respond if you have heard of these before. The other day I was driving down the street and my horn sounded off without me touching the steering wheel. Today on my way into work it happend again. Very strange.

The other issue it when my turbo kicks in it sounds like a screaming banshee. I think that it may be the blow off valve that came from AVO, but I'm not sure. Could it be a broken seal or something of that nature? There does not seem to be any degradation in performance (although I have kept my foot out of it since the noise started to happen.)

My apologies if this post is in the wrong area. (newbie)

Please excuse me....boost guage not controller.

Do you have an alarm on your car? The honking could be related to the alarm...

I would hesitate a guess that your screeching turbo noise is due to a leak at the turbo-downpipe junction. It happens occasionally. Contact your installer and have them check it out.
