W900 that's way too slow.

I'll have a full ecm readout soon, had to find a shop that didn't want to charge me 500$ for the privilege of knowing what my current settings were.

 

Even if 20% isn't viable, 10% is still close to 4-6 k a year in fuel. Rear ends costing more than that might make me wait a year yet, but that's a pretty compelling argument for changing now

 

Well, thanks for the input.

For now it looks like I'll just be doing new stand up 24.5s and just keep my eyes peeled for some 3.36s or 3.55s

 

That's the thing, it's currently running (mostly) closer to the extreme right of the graph, lower torque compensated by the higher hp and much higher fuel consumption.

Even if all I did was bring it to the halfway mark, that's no small savings in fuel, but better yet, it stops running at 1800 rpm and the torque keeps it from being too weak to keep up
