ignition check?

What BJR said. I verify the coil's getting the juice it should with a volt meter. If it seems low (under 9 volts) I'll figure out what's up with the wiring. The orange box pulls out timing at higher rpms too. An FBO or even the Std Ignition stock replacements do not, and IMO are better boxes. I'm not a big fan of Accel either. But if it's getting low voltage, no coil will work right.
