I'm after some help!!
I've recently had my dv valve replaced and have lots more power! Must have been leaking for months! But on a few occasions I've completly lost boost. Absolutely no power. I pull over, turn car on and off, and drive away like normal. This has only happened since my dv was replaced last week. Any ideas? I've got a stage 1 map which has been on there for 12 months or so. Intake and cat back exhaust.
