I am still bone stock. Why is it that some days my turbo is smooth and powerful all the way through the RPMs, and others it's inconsistent? Yesterday I floored it and it felt like it had no power but then the turbo kind of violently kicked in at around 4k or higher but then immediately dropped off again. Why is this? If I had a bad DV, wouldn't boost be lessened at all times? I wish I could get consistent power. Some days it flies and other days feels like a N/A 4 cylinder. What's up with that?
