My busa has recently started losing gain of rpm once I hit 8-9k rpm. At first I would let off the throttle but I also tried to power through it and it just continues to baug. The FI light comes on immediately when this happens. It runs like a dream all the way up to 8-9k rpm. I have not ran the codes so am unsure where the problem is. It's got the big bore kit (1397), gen 2 crank, full yoshi 4>1, pc3, retarder if any of that matters. It's been dyno tuned (but not recently) and like I said runs like a top until I really get on her. I feel like it's a fuel issue, hense the reason I said throttle body issue? Please help and thank you!
