I've run 119.8mph without WMI on E30. He claims 92 octane, fastest we've gone on 91 octane was around 117mph but I don't push it on 91 octane often. So if true maybe that is where his mods are helping? A key difference between BMS and all other tuners on this platform in how we share results is we always post the recorded engine data to support every slip or dyno. What good is a 120mph run or 460whp dyno if you're slowly knocking apart the engine to get there?
