Hey so three days ago I was helped by a mechanic who showed me what to do installing an invidia uppipe, invidia downpipe, and replacing the gaskets (turboxs). Both were catless by the way. The guy who helped me also did the tuning for me (he has the experience). I was driving yesterday afternoon and definitely giving it gas when my cel started flashing. I immediately pulled over, opened the hood, and noticed my engine was shaking pretty badly. I'm wondering if I needed to replace my injectors with better ones and also if it's safe for my car at 18lbs of boost. I'm worried that the tune may have ****ed it up and I need to find a solution on what to do.
