1) Sent your CZ Stage 1.1 back to Canzoomer for an update. The circuitry needs to be updated to help eliminate this problem. You can wait also for members to post pictures of the solution and do it yourself. CZ was going to give an update but he seems to be tied up with other projects.
2) Upgrade the coil pack and get the AEM ignition controller. Check out what Mazdamaniac did with his 8. Ignition Advance Thread
Apparently the problem with the coil pack was always there but the CZ just amplifies the problem.
