stutter problem at 2500 rpm
I had that same problem before Ryne tuned my car. Didn't know what it was, so I just took it like that for a tune. When Ryne was tuning it on the dyno, he looked at it and told me it was 1 of my spark plug wires. The wires were too close to the headers and burn 3 wires. I got new wires with heat sleeves. Problem solved after that.
If your car is due for a plug/wire change anyway, it won't hurt to tackle that first before you start cutting access hatches for a fuel pump install (or do it the hard way and drop the gas tank 
)
) NGK+Whatever brand cables and see what happens.

Yup, check the pressures. Idle and running. . . .
Not that bad to change if you cut a "trap door".
I haven't done it yet, but I looked into it a bit for future purposes.

its like that pump doesn't want to work when its cold but once it runs and if u don't let it sit for more than an hour it starts right up. but over night it cranks and wont start then u shut it off and crank it for like a few sec then it starts. my master tech says the pump is going out. and it has fuel pressure while at idle and running but if u stomp on it it doesn't hit power band at all. probably going to swap out the oe for a 255 with in the next few months.
