I've made her efficient as I could... Edge Chip, K&N Cold Air intake,JET Throttle Body spacer, 3" Magnaflow front to back and full synthetics all around, E3 Spark Plugs.. now @ about 400HP.
If I tow my camper uphill a good hill , like the ones near Thunder Bay or Mattawa, for more than a minute at 105KPH it registers 0.1 MPG or 0.1Kms/100L... it won't go any lower..
I've actually seen it happen....18MPG Bobtail Hwy 11 city is the BEST I ever got...0.1HWY is the worse.
I love her anyway!!
