Hey, I am about to order the portfueler from Hahn and just had a few questions. How does the Aeromotive 1:1 regulator go in? Do you take out your stock FPR? Also, what's the order of the fuel lines, does it go from the pump to the stock fuel rail, to the portfueler rail, then to the 1:1 and then return to the tank? Last, how easy is the software that comes with it to tune if you have a wideband O2? Thanks for any help.
