This is a customer car that came in with a strange misfire issue. We walk you through the diagnostic process and I won't ruin the surprise of what we found!

Then we finish the tune on our dyno.

The customer is so happy with his car running right, he has us swap in a Cusco 1.5 way diff from our time attack car.

Smiles all around
