Thanks for the reply. Not sure where you got 116 octane from, but it wasn't me, although I did mention a splash of 110 for MY car.
Definitely not draining the tank, but I am going to have him run it low, then put some 100 octane unleaded in the GTP...probably 5 gallons and even if it has 2 gallons of 93 in the tank, it'll still average out to 98 octane which should be golden. He gets very little KR, even in the summer, with pump 93. We just started with the "winter blend" gas, so I'm not sure what that will do???
I haven't heard anymore pulley talk, so I'll just datalog and check for KR and probably just add a couple degrees of timing....or not.
