That little red tick records the highest value, I've seen it spike above 20psi ~3-4 times but haven't actually caught the gauge doing it. On my way home tonight I gave it the beans in 1st and actually caught the gauge jump up to 24psi for a second.
Wazzup with that? A stock GTI only maintains 10-12psi and should only spike to like 14-16 from what I understand, even a tuned car shouldn't be going above 20.
I'm wondering if its a false reading, I've heard the app can miscalculate the boost if you don't have it configured correctly, but it does show expected values most of the time. Lets say its not a false reading and I am getting a nasty boost spike, what would cause that, bad DV valve? I'm a complete turbo-noob.
I know the DVs fail on these cars, and the upgraded replacements are actually pretty cheap, but I haven't heard the "fluttering" that's supposed to indicate a bad one.
