hey guys im going to get the m2 flash from jestr tuning soon, my mods are hks rs intake, super sequential blow off valve, 3 inch test pipe, 3 inch catback, hks eids, he said with those mods i should be around 280 or 290whp at 21 or 22psi and when i get a downpipe i shouldnt need a retune. my question is do i need a fuel pump before i get a flash like that because some people say i should and some people say ill be fine, because i cant really afford both right now but i want to get some power out of my mods. thanks for any input guys

 

you don't need it but it is cheap insurance
