For those of you who had the Uprev tune, what did it do to your MPG? My stock tune was a little too rich and I assumed the MPG would go up a little after leaning the A/F ratio. But I lost about 2 MPG with the tune. I can switch back between stock and tune so I have been able to verify the loss in MPG.
