I also wanted to mention that the Siemens injectors give incredibly smooth idle. The tuner was able to get the idle down to 750rpm with a mild cam.

Got to the Whyalla 1/8th mile yesterday, horrible conditions 40 degrees with high northerly winds.

On the bright side 8.3 seconds which is apparently close to pushing into the 12 second 1/4 mile mark.

I just Went back to letting the auto shift by itself as I was having traction problems doing the manual shift without slicks so I know there is a lot more potential in it.

Cheers, I also need to learn how to drive. Ha.

Also Losing a fair bit of coolant as I suspect either the head is lifting under boost and/or the surface finish on the block is not good enough for the MLS head gasket. Fortunately it is not fouling the oil from what I can see. I could feel it slightly missing during the runs which I first thought was maybe the rev limiter activating but now i reckon it may have had something to do with this problem. There is no coolant loss when driving on the street.
