Tuning with jets, Power valves and an O2 guage

Well crappomaggot, that's the problem. You got it comin in too early buckwheat. Too early and too much. That's what she said last night. Try having it all in BY 3500. Then if that doesn't work, 4K. There's no hard and fast rule that says it has to all be in by 2K. That's just a number you seen thrown around a lot.....and it's usually for lower compression engines. Because they need more advance sooner for more cylinder pressure and more bottom end torque. You got plenty of cylinder pressure. Try curving it so it has like 20 initial and then all in by say 3500 and see what she does.
