> Got the gauge, installed it, works perfect no problems or leaks, but one question…how much psi should stock k03s push? Mine reads 12-14-15 psi on WOT no lie, unless you have to adjust the gauge and about for the negative side it reads about -15 regular driving…Or if i even have k03 turbos?

Welcome, another s4 owner! That sounds a little high for stock ko3s with no chip. Is it steady at those numbers or is it spiking? 15 in vacuum is about normal.
