I have my max mileage for sale. I missed my XZT so I went back to the X2 100HP chip. I downloaded the M3 tune on my x2 so I dont need the M3 module. I got a solid 1 MPG all around with the chip. shifted better and ran a little smoother. fits 04.5-07 dodge 5.9 CR $120 shipped
I just want to add that this module can be updated to the XZT for $90 through quadzillas website. So if your looking for the XZT+ (65hp) you can buy this and upgrade and still have spent half the money for the XZT. I do have the Milegae tune on my X2 as it does work
