A friend of mine got a diablo with the last update we turned the DOD off ,the speed limiter off and the fan speed. there are 3 more things forgot them but there is a spark something , converter parameters fuel something and rpm parameter I dont know what to raise and howmuch to raise things the problem is that we want to have some power out of it but he doesnt want a custom tune .

So can some1 help me to adjest these things?

 

Why not a custom tune? Alot better than the Predator..
But if he is stuck in that rut. You can add some timing, few degrees and go from there.

I think you can scan with the Predator? If so drive around and watch for Knock retard. If you see any its prob cause the timing is too high. I wouldnt mess with the fuel unless you have a Wideband.
