but I never paid it much attention because I always figured the stock gauge wasnt very accurate. But now that you mention it, I kinda wonder why my gauge is so active. I noticed it after I gutted my precats, added midpipes and aftermarket catbacks. I also have a cone filter and Ash ECU. Funny thing is, I never got around to adding boost jets, and I've never had a boost controller. I know the car is stock because I bought the car from the first owner, bone stock. I guess the mystery will never be solved :/
