Re: au fairmont V8 vs. au XR8 220kw V8?
Any car with different power than another factory car is always going have the computer changed slightly. I beleive that the 220kw motor had 1.72 Roller Rockers, slightly larger intake and exhaust valves/ports (same heads though, all GT40 for AU's). The cam specs are different too, I'm guessing it's due to the grind of a 220 cam to give it slightly more lift and duration. Other than that I'm not sure what else.
