GDE Tune Quick Results

[Rusty PW]

Drove 1500 miles over the last couple days. Loaded for camping, cooler, wood, water, etc. Heavy. Didn't hand-calculate anything but got truck-reported 22 mpg driving for a couple hours across the rolling hills of southern Missouri, 60-65 mph. 20.8 mpg with the cruise set for 70 mph all the way back to Minnesota. With the way my truck is outfitted I used to get closer to 18-19 mpg, so that lends credence to GDE's claimed 10-15% mileage improvements. 37s at 34 psi hot, btw. I was hoping after tune and gears 22 mpg might be possible on the highway in current form. Well I don't have the gears yet, so it might be close.

All EPA equipment is still intact and working.

Didn't notice any regens happening but on the highway the DPF SL dropped to 11% on it's own with regen inactive. Is time between regens a reported metric? I've never looked.

I did not get a clone of my original PCM. Now I'm seeing the concerns over fuel dilution and increased aluminum in the oil with the GDE tune so hopefully I won't regret that. I do send all my oil off for analysis, so if something changes I'll see it.

Stock. I'm getting around 700 miles between regens. It doesn't matter what my SL % is. Last one was at 52%.

Of course more mileage and power is always good but the two things I’m really interested in is engine braking off road to crawl downhill and reduced turbo lag.

@BlueScapegoat what’s your sense of the lag and if and when you have a chance to test the engine braking (assuming you opted for that, I think, option), let’s us know how that works, or anyone else who has experience with that feature.

So in the second video I posted you can see how much actual turbo lag is left. I stomp my foot down and it rolls out slow until it spools up and breaks the tires loose. Or, at least, that's what it feels like. I can mess around with it some more in the coming days and watch the boost gauge. Once on my trip I had to shoot a gap in traffic at an intersection and I slammed my foot down out of habit from the laggy OEM tune and ended up roasting the tires in the turn. It doesn't pull power with the wheel cut like the OEM tune does. Or, at least, not nearly as drastically. The 1-2 shift happens really quickly as well.

I did opt for the engine braking. I'm not sure when, in drive, it would've ever actually get used. But I was having a blast in the hills manually shifting it down to activate it. It works well. I'm excited to see how it does with a trailer behind it. I'm sure in 4lo it would certainly assist

Yea… the stock tune definitely either takes a second to decide if it’s gonna go balls to the wall or just does it … annoyingly.

15.1mpg?!?! Good god man! Doing 0-60 runs all the way to work or something???

Ive been in a stage 2 and the GDE. in my experience there is a big difference between the two. almost as big as GDE to stock.

I'm impatiently waiting for the first one

Let us know how that goes …. EOC???

yes. their communication sucks but nobody does what I need to make the new suspension work domestically. I don't know what the 0-60 time is but I can say the Gladiator I rode in had 43s/ tons and 5.38 gears and pulled from 30-65ish with the torquey feeling some of the EVs ive been in exhibit going from 70-100ish. (not like a cybertruck or a plaid. more like a non GT mustang mach E). The wranglers I compared GDE and EOC directly to both had 37s

Update. Same rig, now 40s and 4.88s. MRTuning stage 2. Off idle pull, no brake boost. 4wd.
