EFI Chip For XF Modify....Help!!
I have a 1987 XF Falcon with EFI and i know that it is possible to change the EFI chip (the chip that regulates the air/fuel intake induction...) but im a no expert, but is it possible to get a Modified Chip to increase the fuel/air intake and thus increasing the cars power?? i Know its possible, but im not sure about such an early Chip the XF is using.....if so what do i need and how much..and roughly how much can the cars power be increased by....(currenly it tops 121kW and 325NM..it uses the last engine they used on the XF as follows:
4.1L Alloy Head EFI Unleaded 6 cyl
Bore and stroke: 93 x 99 mm
Power: 121kW at 4000rpm
Torque: 325Nm at 3000rpm
Pushrod overhead valve, 2 valves per cylinder
Fuel system: EEC IV fuel injection
Compression ratio: 8.7:1
Thanks heaps for your time...
