Ok so I've read this whole thing, it looks like something that anyone with half a brain mechanically can do, and something that EVERYONE should do.
Personally, I put down 404whp on pump gas @23psi, and I have upgraded fuel mods accordingly. I honestly don't remember correcting this though, and with the amount of work involved I feel like I would remember it. If I'm not having any fuel issues with the car, would you recommend pulling the pump and doing this mod anyways? Is it something worth checking for to see if it's even done or not? Any input is appreciated!
