Poor Bugger, sound's like you have been through hell with the build but im sure in the end you will be more than happy with it...

Race fuel tune is not worth worrying about unless you plan on racing often, I would be more focused on getting as much as I can on pump and possibly an E85 tune aswell...

Im very interested to see the outcome you achieve, as I have nearly exact same combination, only difference being mine's an Atomic 998GTR and ive gone larger turbocharger (GT47-88) so im keen on seeing your final result's both on pump fuel and race fuel, im most likely going to have mine tuned for straight E85 seeing's as Caltex are releasing it this month and the servo is less than a kilometer away and another is about 5 kilometer's away so it's nice and close...

Im only fitting it into my Falcon for awhile over the Xmas period until my other car is done then im swapping it into that, that car is going to be atleast 1000lb lighter than the Falcon so it should be interesting ride...

Goodluck with it all...

Final power figure is around 450 - 470rwkw's at 20psi.

Due to the diff gears the car is maxing out 4th gear at around 190km/h. Hi Torque said this car was throwing ruber at the rear wall of the dyno cell.

I'll let Matt elaborate more when he jumps on but I believe he's off to the drags on saturday night with a set of MT's to see what the mph is on this car to get a better idea of its true power levels.
