Anyone know what the drive train loss is for torque? Is it the same as for horsepower? I had my 2013 gt500 dynoed and it pulled 633 ftlbs with just a 93 octane tune. If you use the 10% loss that these 13s seem to have on horsepower, I come up with 703 ftlbs. A 70 ftlbs increase seems an awful lot for just a 93 octane tune.
