Been running Cobb ots stage 1 87 octane. Because of heat and poor fuel quality in AZ. Now at ots stage 2. 93 octane and its adding timing on a 115 degree day. Forgot how good it runs with some timing .

I notice a difference between the 91 and 93 ones. I have 93 here but thought the 91 might be safer. I’ll just let the computer decide and set it to the fuel I have. Knock protection is so good anymore anyways.
