Anyone have real world experience or data (seat of the pants is fine) when upgrading from a 52 to a 58mm Throttle Body? If I'm gonna do it, now is the time when the head is off and the driveway is already covered in metal slivers It's for the 8V motor in my 86S, not full race but fully ported head(stock sized valves), TU Header, GT 30, decent FMIC(for an Omni lol)
