As stated above by several members, no need for inconveniences such as an aux low side pump or another ECM to control port injection at this power level... but if you want crazy high hp like Josh, you need a wilder setup  |
And this was my original idea without the voltage booster, but the freaking hpfp is crazy expensive right now
