At first I was really mad at superchips. After 5 or 6 phone calls. I finally got my tuner fixed. I had the tirepaq & paid to have it upgraded to the full fledge tuner. Customer service was iffy. But finally I got things to work. I only have done the 87 tune. This summer I might play around with it more.
I have a 05 Ram Hemi 1500. Before the tune, I was useing 87 octane. Once I got the tuner to work. I changed it to the 87 Octane.
Before Tune: 11 MPG or a little less, this is with leting the truck idle to warm up this winter.
After 87 Octane Tune: 12 - 13 MPG. This is with morning idleing. So the darn thing actually works! I see people complain about not geting better mpg. I don't know what to tell you. Mine works great. I can't wait until summer rolls around and I take my winter tires off.[/url]
