If it's about Power Wagons, all generations, this is where it'll go. This is the original PWR Forum Power Wagon Technical Discussion Section. And this includes everything that doesn’t fit in any one of the other categories related to the truck goes here!

Correcting the computer running is more to me then just being off by a few km/hr, I also want to correct it so that my truck still uses its MDS function so I can maintain my 20mpg vs 16 without the MDS.

Which exact part of the pinch weld do you guys have to trim? Someone got before and after pics?? Anyone try the 37s on stock rims? Or how to stock compare to your aftermarkets that have 6" BS?

There are pictures of the pinch weld cut in this thread: http://forum.powerwagonregistry.org/vie ... f=2&t=2714

There are some people in this forum running 37s on stock rims. The stock 2015 PW rims appear to be 6" backspace.

I am going to be in contact with my dealer tomorrow to see if they can accommodate a computer update to 37" tires. If not, it is an +11% difference in speed from stock, so it won't be hard to manage until someone makes a tuner.

Diablo sport makes a tuner. I bought it when I bought my truck waiting for updates... Finally got one to find out the OEM ECM can't be tuned on 2015s. You either have to send Diablo sport your ecm to essentially "jail break" it or buy one for $600 in order to tune using there software. There are no other tuners I know off or I would buy them.
Which also makes my tuner a $500 paper weight

It looks like Hypertech has a speed only modifier for the 2015 RAM 2500 5.7L and diesel, but not one specifically for the 6.4L. I didn't get a chance to check with my dealer today but still plan to do so over the next couple of days.
