Searched but cannot find definitive answer seems like there are two sides to this. S13 Redtop was tuned with a Walboro 255LPH. Recently I decided to go with a beefier Denso 1040 rated at 300LPH. Will that throw things off ? Will I need to retune? Stock FPR, Stock injectors, stock everything. Thanks in advance.
