I had the car at a dyno shop in Spruce Grove. They installed the turbo and dyno tuned it. I went to pick it up and it acted like it was missing until you floor it then it turned on. He added timing and adjusted MAF and then it seemed fine. I trailered it home and ran it 2 months later and same issue. The shop is 6 hours away so I want to try and figure it out. It acts rich . Any ideas guys ?
