Allright guys I know this has been talked about but I need some advice. After the exhaust and intake im kind of tapped out for cash. I can strecth and afford the edge now and nothing else for a bit or get the MP-8 now, have money left over and get some other small accesories. Do I go for more mileage with the MP-8 or go with the edge. What kind of increase in MPG is anyone seeing with just edge. Im talking over and above the increase from the DPF delete.
