QUESTION about MSD 2 Step causing misfires on 15 PP GT

[blusdacolor]

I purchased a MSD 2 step for my 15 Gt, its a pretty straight forward hard to mess up install. ( Remove coils, plug the MSD coils in- wire to ground and clutch) All plug and play. So I installed everything and tested out the 2 step after I got it hooked up, it engaged properly. Took it for a test drive and my car ran like garbage, got multiple misfires.


So I took off my cai, flashed ecu to stock and it ran fine. Installed the cai- retuned to 93, still runs fine. I then put on the 2 Step thinking it was a fluke- misfires terribly. I would appreciate any help! My thoughts are that the box itself is fine- there is an issue with the coil plug or wiring.


Im Bama tuned, long tubes, comp cams, MAK performace cat delete, and a CAI.

Set at 4k RPM (Before I test drove I did 3-4-5k RPM tests)

Thank you, but it seems that is just another way to wire it to ground. There was no activation error, it works fine. It is causing misfires.
