Jumpy RPM ??? HELP !!!

[G2_integra_GSR]

i have a 94 gsr swap in my DA9 and my RPM seems to be really jumpy when my vtec hits does anyone have any idea what it might be or is causing it to jump ???

if it jumps rapidly, as if a surge or something, then you have a problem in your distributer. check loose connections or exposed wires.

does the car jerk when the needle jumps or is the needle jumpy without affecting the way the car drives. If you can feel the car jerking as well i would check the dizzy first as already stated
