Honestly, you are right on the line at 260F and the ECU is probably holding back a bit at that temp. For reference, I run ACS Roval at 2:08 with no power mods (stock intake and exhaust). My temps peak at 230. We're in January, but you can imagine running ACS in July when it's 90F ambient -- you would hit full limp mode (3000 RPM restriction) very quickly.
