^ Aye, like hitting a brick wall. Got a ride in a turbo Celica a few years ago and we hit fuel cut just as we hit 100 mph, scared the shit out of me.

A97, as for the FCD, if you wire it correctly there won't be any risk of fuel cut at all. It clamps the voltage from the sensor, so there's no possible way the ECU will see boost. I was originally gonna do the ML but heard stuff about the filters getting dirty all the time, I'd rather just solder some connections once and never have to worry about it. The instructions are super clear too.
