Installed Gforce chip in my 6 Spd Challenger..Drove car to Newfoundland and back to Elizabeth City NC..While in Canada,on the QEW in Nova Scotia and New Brunswick,using regular gas and driving at 70 MPH,I recorded 28.7 MPG on multiple fill ups..In the states my milage went up to 24.9 MPG..Reason was that Canada wasn't using ethanol enriched gasoline..I have been so impressed with this chip I have purchased one for the wifes 2012 SRT8 Charger.I am sure that it will perform as well as the one I installed on my Challenger and sone 5.7 Ram truck..
