I've seen some on EBay etc, but aren't they tuned to a specific state?
If you aren't running the same gear & PSI etc, then it wasn't going to be worth it.
Haven't seen them go for cheap though....
I would be going for a reflash still.
I know you're in Qld, so don't have easy access to him, but how about a Dr Drift remap? He does head up to Qld every now and then to do tuning. He already has experience with remapping VR4s and told me he loves doing Mitsis now that he has the gear. It might be worth giving him a yell and seeing if he's due up your way any time soon...
LOL @ NOS.... pass thanks... I don't fit the 'vin diesel' looks category or drive a red FD
