I get the stuff from the track. It says SUNOCO & they told me it was 109 octane. They probably have their info wrong, the guy who pumps the gas isn't the brightest.
As for the car, I have now completed 2 whole race days for a total of 143 laps, placing 2nd the one day & 1st the other day & not once has the car hiccuped, sputtered or gone into limp mode. So I feel safe in saying that as of right now the problem is fixed.
Although one of the other, one of the other Preludes running out there decided to take his power steering belt off & in practice his car started doing the limp mode thing. I told him to put the belt back on & so he did. He went out for another practice & the car was fine, he never hit that limp mode again the rest of the day.
