The motec has been used on a speed 6. They did have to integrate port injection, but I bet that was because there were no fuel upgrades that long ago. It did still control the di up to a certain rpm though, so I imagine it would work with you having the upgraded pump.
That, or maybe the cost of a plane ticket for one of the pg guys to come to your city to tune it would be alot cheaper. They'd get it on the road and driveable at the very least. I would see about upgrading the standalone though. They've added some neat tricks from what I understand.
