Unless you compensate for squish, your PCM will think each revolution of your wheels moves further than you are actually traveling. That equates to to a higher speed than you are actually doing. Try it with 2659. If you're still indicating faster than you're actually moving, reduce it still more.

Oh, and Lars was correct too. Make sure your Gear Ratio value is correct when you do this.

I just checked the setting and put your new number in. the gear ratio was correct at 3.73 so ill give you number a try and see how it goes.
