782 on fuel...lil ol Dmax...

Good number on the dyno.....pulls like a train to 4300 RPM, starts falling over at 4400.. fuel stops at 4500. I think that needs to be changed... I think EFI lets us go to 4800?

Cant get the turbo to light on the line, still playing with that. Only 4 passes, best was [email protected]
2.15 60'

Dunbar pulled on it three times. 95 degree's out and heat soak prohibited a 4th pull with different tune. Only got to run the "small" side of the DSP2 switch
