"This is my second Gforce chip. The first one was installed in my 2008 Chrysler 300C with the 5.7 Hemi V8. I noticed an immediate difference in the power. I went from barely getting 21mpg to 29mpg Highway. I drove 60/65 mph. I also noticed that the transmission shifted better, much smoother shifting. I was very happy with the way my car performed.
Now I own a 2011 Dodge Charger Rally Plus with the 3.6 Liter V6.
I ordered a chip for this car and had it installed today.
Same thing, immediate difference with performance and the transmission shifts as smooth as silk. If I wasn't concentrating on how it was shifting, I would have thought it was a brand new upgraded transmission. I almost couldn't feel it shift through the gears.
I'm sure my gas mileage will improve. The best MPG (before the chip was put in) highway I've gotten so far is 32.5 driving 60/65 mpg. I'm averaging 21.5 city. The sticker showed ratings of 17/27.
I highly recommend the Gforce chip."
