That makes sense, it's the first tune and the first time I've ever done anything like this. He did ask me pretty sternly about the quality of gas I was using. He said I was getting a lot of pinging and I told him I was using 87 from Sam's club. And he said yeah the stuff from Sam's club and Costco is really cheap gas and he said I needed to go up to 89 at least so I did.

If he advised you to upgrade the quality of your gas, do it.

These things need 89 or higher in stock form, especially if you put it under any load in hot weather. Accelerating up a minor grade in NC during the summer can make it knock on anything less than 91.

Sam's gasoline is not Top Tier rated. It could be, but it is not guaranteed. Quality also makes a difference, not just octane rating.

Timing on mine is aggressive, while I cannot hear any knock, the Tech-2 will show it on WOT runs with 1-2 degrees of retard on 93 with Lucas Octane Booster. Can't wait to switch back to E85 soon. We need the range.
