Has anyone had experience with the new GDE EPA compliant tune? I’m just curious. Knowing GDE, it’ll be great.
Just did my first oil change with the compliant tune sent for analysis. Will post when I get it back. The oil was definitely black. Haven’t seen it that black since before the the original tune. Still love the tune though. Trucks drives so much better.Can someone tell me how your oil looks after driving a while? I am wondering how much different the soot is in the oi versus stock and pre-compliant GDE. I have a related post over on the tuning section where I would like to see an oil analysis. Thanks

What tune?It took me 30,000 KM’s plus before I started seeing cleaner oil after my tune.
Now it doesn’t turn black until well north of 7500 miles on a change.
When you go into the device it should have both the original and GDE tunes. Select the OEM and re-flash. It will do the ECM, then the TCM.I have the GDE EPA Compliant tune as well. What exactly are the steps to swap back to the factory tune? I haven't tried yet, but I assume you plug in the tool, put vehicle into run mode, then what?
