Hello Twin Turbos, 24 valves, 4 litres, BIG FMIC and a after market ECU.
What airbox (Pod or cold air) and a 3 or 4 inch system.
Power is at the calling.. these things are going to be fast.
I have been told the BA ECU's are reprogramable using the Ford ECU computer thingy in the workshops. Much like the Gen 3 ones are in the Commodore.
