So I’m trying to figure out if my car is tuned or not, I bought it used. I have a Gen 3 2013.5 GLI. I don’t have a boost guage, OBD Fusion is showing 18 psi, anyone using an obd scanner on a tuned motor have any numbers? Car does not feel like stage 2 even with those numbers, could boost curve still be in the car if previous owner detuned it? If not guess it’s time for a real boost guage.
