The tacho acting up is a symptom of a bad Voltage Regulator, you can check this by measuring the voltage across the battery with the engine running. If the VR has failed you will be overvolting (Should read 13.5-14.5v).

Under load you are pumping a lot of fuel into the cylinders and it requires a strong spark to ignite it. It is possible that overvolting your permatune under load is the cause.
