regardless of fuel used...you'll still need to do timing and fuel sweeps to find best power for any given octane.

My buddies was the same way

I only didn't speak about timing because of the title

But I agree you can't have one without the other, they are dependent

Now we got some good info in this thread.

Earlier someone mentioned that using only water in the water injection system robs the car of power but keeps things cooler. Is this really true.If your running cooler and able to advance more timing how can you be robbing the car of power, I figure you would be making power.
