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?
