^^That car is amazing,
But.. He is getting a lot of Knock. Note the light on the dash, the flashing one, It's the check engine light. He probably flashed the ecu or has a stand alone that flick that light at every knock he gets. He is getting 10-15 knock at lower rpm (probably running too rich), then up top he's getting 3-8 knock before he hits the limiter. I've never owned a supra and I know they are very solid, but that's a lot of stress on the drive train and engine. Maybe he should be tuned more conservatively, let's say 800whp and actually put some of it down.
