Unless you owned the TT370Z, it's difficult to completely understand the relationship the owner had with GTM, whether the owner was an idiot and went against advice, or it was retuned, and done incorrectly. Only a complete moron would push 14:1 AFR on any vehicle, let alone on a turbo car.
Please just stay on topic as a lot of us can care less about how you feel about GTM and more about your results
