I went with Tapout for two reasons. Reputation and the fact that Scott continues to push the platform forward not just in tuning but with hardware development. My experience with Scott has been nothing short of spectacular. He had always been available and has sent me revisions at 9 pm. I had issues with misfires after changing the plugs to Brisk and he sent me a new set to be sure they weren’t the issue. Scott even took the time to message me happy birthday. I was pretty surprised by that. In my opinion he wants to see everyone happy with their car and will do whatever it takes to get you there.
