How accurate are the stock boost gauges? It doesnt really show a number, per say, kinda just shows how much. Would swapping in and mounting an aftermarker one be a more precise way of seeing exactly how many PSI? Or should I just save up for an Aeroforce gauge?
Here are what I was looking at (gonna try on Ebay).... these are a lil more affordable for me right now than an aeroforce gauge... I wanna know exactly how many, thats all, I figure a more accurat reading will help with modding
