00 Busa sputtering after 5000rpm

[broseboro332002]

I adjusted the TPS and made sure all vacuum lines were good to go. I launched and left the opponent sitting then got to around 10000 rpm and sputtering so I back out of it then hit is again and at 5000rpm she sputtered again. I am at 21605 miles do you think I need a valve tappet job or throttle body sync? Also on the 2000 busa the fuel filter is internal so I was thinkin to making a external mod do you think that may help?

I'd run a search, as there are dozens of these threads just this year. Try out all of that stuff and then report back with what you've done and what problems you still have. Lots of peeps have had sputtering, lots also have a 5000rpm or other rev limiters.
