I GAVE my POS unilites away dual ballast eye burning junk.
I was getting them complete at cost, and after the second eye died I had had enough because the eye was costing me 25$ less than a whole new dizzy.
Then the new mopar performance distributors were made by Mallory and the advance weights are believed to be to light however the two I have work fine.
I have an MSD pro billit and it works well, the MSD Ecurve works very well for me and super easy to tune.
I believe you would do well with a Firecore as well.The only experience I have had with them the service was exceptional the quality superb.
