Smarty Jr and MPG problems
Hey guys,
So for a good while after I got my smarty JR. I got great MPG. 17-18 range. Before I got my lift and tires with out the programmer I got around 20. But here is my problem. My MPG has been decreaseing over the past few weeks. It dropped to 16 then 15 then 14 then 12 and now my last tank was 11.8 MPG. I have tried several different setting on my smarty. I found that the truck liked SW2 TQ2 TM4 the best for MPG and over all power/tranny response. I was getting 17-18 on those setting. But my last tank on those setting was 11.8 as I said before. Any idea`s as to why the major drop? All those numbers are hand calculated as well. I try not to drive it hard and I have not been driving any differently. Thoughts?
