So first off stock redtop, 10psi, exhaust, frontmount, walbro 255,

When I get on it and my rpm rise to about 4-5k my motor shutters and sounds like its missing. Like it instantly has noo power at all. I replaced my fuel filter. What should i try next?

Bad coilpack, wiring problems, loose MAF wire - there's TONS of reasons for this to happen... sadly, they're really hard to troubleshoot. Search around and make a list of all the things to check - eventually you'll find it.
