2.7L engine Tune?

[BAM]

Disconnect your battery and there's a lever on the top of the ECU plug that needs to lifted to "unlock" it then you can pull the connector off.

Keep the updates coming on the 2.7 Tune. I am going to update after hunting season.

 

[BAM]

Got the tuned ECU back and was only able to take my Roxor for a quick drive (Had to leave town for work). But right off the bat acceleration was much better and obviously more power. I was able to pull a small hill without downshifting out of 5th when normally I had to slow down and shift into 4th. Had the power to pull the hill and the power to accelerate up the hill without downshifting. I run 32s and was getting up to 63 mph running at about 2900. It was a short drive though and I pulled the ECU and sent it back to Wade to get updated as the check engine light flashed like others have stated. Should be getting the ECU back tomorrow and I plan to do some more testing in the mountains if I can get the chance weather permitting. But from what I gathered on that short drive the tune is well worth it. I'll report back after more testing.

That is good. Offroad in the hills always having to downshift. Hopefully this will help.

Running the 2.7 Tune now on the 2024 with stock 5.38 gears 235/85 16 tires. Already got it to 60 easy when it was a real struggle to get it to 50ish before. Much better acceleration. I keep the 5.38 gears for offroad in hills.

I tuned my 2024 2.7 liter. It has stock gears and stock size tires (235 / 70R16). 65 mph is easy. 60 mph at 3,000 rpms. I can’t wipe the smile off my face. The Diesel Freak tune totally changed my ride. I love it.

 

[Gabe]

Yep. It is big improvement. I can't wait to get it back off road but right now in shop.
