I just purchased a 300zx that reads a negative boost when the turbo kicks in. The seller told me that apparently the previous owner installed the aftermarker turbo gauge, he wired them wrong. So now the after market + the stock one shows a negative reading when its suppose to be giving a positive. How can I rectify this issue?
