 hpfp line upgrade 1.1 So I bypassed the stock hpfp connecting line from bank 1 to bank 2 seemed to solve my low side fueling issues. More to come. Plan to bypass the other oem steel line to bank 1 hpfp will log for results. This was in 8°f -3800 DA very happy with these results! This log shows a max boost 27.99psi |
