car was tuned by scott siegel. car runs great. tuned for 20.5 pounds of boost. my prosport premium boost gauge always read 100% accurate. Well, i decided do push the car a bit. Havent done it lately, trying to save gas. my boost gauge is reading 22 pounds. i doubt that its reading wrong, should I be worried? Im supposed to be taking the car back to scott for a fine-tune, but im really tight on money. what are so possible causes of this? Wastegate getting stuck? any help would be appreciated, thanks guys.
