I have a stock DP installed - against recommendations - but the log seems fine to me (at least the 98 Octane one). I would like to hear an experts opinion about that.
first run was 57% e30 tank (91 + e85) to 91% full tank (+5 gals on 100 oct), second run is ~90% full tank with +1.5 gallons of e85 to balance out to around e30
first tank should have been around e24-e25 i believe
