Checked the data log and it also show 15.1 AFR. Advised the customer that we were uncomfortable tuning the car at this time since we felt the motor might be hurt or will be hurt soon since the car has been run this lean. Coyote motors that see heat of 15.1 AFR for any length of time will have a very good chance of the number 8 problems very soon. We choose not to be a part of it,

Good luck and hope you beat the odds

Now it makes sense. Just because it passed the leak down test doesn't mean that there hasn't been damage to weaken the cyl already.

let me ask this...Being what Travis knows and what he has done to mustangs do you think he would volunteer to dyno tune the car and put his reputation on the line if the #8 cylinder was hurt? I seriously doubt it...
