powergrid and promag44

I have a blown TFX hemi with a 44 promag and a 8147 box. I tried installing a powergrid to be able to 2 step the engine etc.

But When i try to run the engine with the powergird connected it is unable to run decently, it stumbles and rpm goes up and down. If I disconnect the powergrid the engine runs like normal.

Is it not possible to run an ignition like mine with the powergrid or what gives?

also make sure the black wire is grounded and the orange is connected to the heads grounded...

Thank you for a quick responds.

I forgot to mention i am running without a crank trigger. getting the signal directly from the promag44 generator.

Both the heads are grounded like the diagram.

And the settings seem correct.

Could it be because i run without a crank trigger?

No retards yet, only the limters this was the first time we tried it, we had to disconnect it to just get it to run.
