Hello Loren and thanks for the link and input. I actually have been to that site and read the data and it's good to know about the perils of too advanced timing. I am hoping someone else has used both the 91 and 93 chip and could share their opinion. Perhaps I will be the one to do this. I did toss 20 oz of Techron in a full tank of 93 octane before I installed the chip and am wondering if that may have some effect on the gas and it's octane level. I will run the tank out, although the manual states to run it to 1/2 level then fill it up again, so It will be a bit before I can rule out the Techron. I will not make a decision on upgrading to the 93 chip before I have spotless fuel in the present set up!

Safe motoring
