I posted the other day about my doofus of filling my tank with 87 instead of 93. Well, I ran the 87 out of the tank just by driving around last week. When the needle touched E I filled with 93. I figured it would take a while to run the little bit of 87 still in the lines so I waited to lean hard onto the car. When I did it's still bucking and popping. The funny thing is I'm not getting knock. Is that because of the alcohol? I thought if I was having octane problems it would be because of knock, but the scanmaster isn't showing anything unusual. This is only happening at high revs and any boost amount over 13-14lbs. One time it bogged in 2nd and I felt like I had no power at all. I'm going to try to add some Xylene to the mix and run out this tank, but the no knock part has me concerned that it's something else. Any suggestions?
