Ok I knew you were doing something way wrong lol. You can export to Excel and note the start/finish of the 4th gear pull. Delete all other data except for a single 4th gear pull. I should have been more specific.
Those numbers sound more realistic. As a comparison I'm seeing 325whp/378wtq on 110 octane. About 10-15 whp and 25wtq loss for every 10 octane points dropped.
