Since my rebuild, I have notice that after 5500Rpms I'll have a boost for another 500rpms and stop at 6k,so I don't know if it's right or my timing is off,I have a solid idel,or I'm reading to much into it.1993 Ka24deCP PistonEagle Rods,Stage 2 Crower cams,(NEXT Mods)Stainless Steel Valves(Oversize)Brian Crower Dual Valve Spring + Seat + Retainer Kit

Sounds like a grounding issue, or your knock sensor is pulling your timing back. Are you getting any codes?
