2014 ram 1500 sport Diablo T1000

[Black Magic]

First post, I had my truck lifted so I could put on my new fuel 35 inch tires. I got a Diablo trinity T1000 tuner. My tuner is ready to go after a long walk through. My question is I now need to recalibrate the speedometer an I think I have to reset the gears cause my Ram is very sluggish. I use to get 17/18 mpg now im lucky to get 13 mpg. Can anyone tell me what I have to set my diablo t1000 to That would be so great if I could get some advise or help.

Welcome to the forum!

First I'll say..did you really think you'd get the same mpg as when you were stock? Expect at LEAST a 3.5-4 mpg drop with a lift and 35's. You don't lift for good fuel economy..but I'm sure you know that already.

With your tuner you can't tune the transmission. The only real think you can change on the tune is throttle boost. You won't notice a difference with that though. If you want to get more power than do these 3 things:
1. Contact Hemifever and get a custom tune done. You will notice a difference over stock. My truck will do a 6.4 sec. 0-60 with my 35's.
2. Put a CAI on. Vararam puts the most power down. I went with S&B.
3. Cat back exhaust. More air in and out

Now to adjust the speedo you'll need to go into the area where you change the tune. Then click (I believe) modify. Then you'll see where you can adjust for the new tires.

If I drive strictly highway doing 90 kmh on cruise I can get 11.7-12 L/100 kms all day. I usually average around 14-15 L/100 kms over the whole take though because of in town driving.
