In June of 2019 in purchased a new 2018 ruby red lariat diesel f150. Really like this truck , watching forum for long time. added some accessories and GDE program , with exhaust brake. I pull 8000 lb travel trailer works great.

Welcome! How are you liking the exhaust brake?

I bought my 2018 Ruby Red about the same time you got yours. How many miles do you have?

I like brake slows down truck much better, was in black hills and used it a lot with and without trailer. I have 48k on my truck.

Please provide us more feedback on your GDE tune and exhaust brake (hot topic recently)

I’m not usually on forums but decided to join. GDE tune makes more power like it and trans tune changes shifts so no more 1 to 3 to 5. Don’t really see a change in mileage. Think there’s less regenerations , hard to tell. I had a scorcher program before , had power but had to play with settings . Not really Great.

Do you have FORScan or OBDii Monitor to monitor your Regen status and distance between regens? This is probably the only way you'll be able to verify their claims of longer distances between regens.

I have the GDE tune and use OBDLink to monitor regens (duration, frequency, etc.) among other parameters. I can tell you that while the regen duration didn't noticably change, the frequency definitely did- the truck went from regenning exactly every 300 miles no matter what to averaging ~450 miles between regens. For reasons unknown, however, the truck regenned after ~150 miles the last time. No idea why.

I do not have FORScan , yet , but have a obd tool that puts out exhaust temp as a pid . Seems when in regen exhaust temp unavailable, and keeps running at stops. Also when on freeway looses 3 to 4 mpg. Just not quite a science to timing of regen. Have been considering getting FORSan.

How do you like the GDE tune? I have been looking at it just to get the brake . I really don’t want the tune itself. But it seems to be the only option. You can purchase just the tune or the tune with an add on for the brake. Can you explain how the tune and brake are installed? Was it two different installs? Or just one for both?

Like tune , more power , better response. The brake good in hills and when pulling trailer , must be in tow haul to turn on. Can buy just tune or tune with brake . The tune includes trans. tune ,can use engine tune alone or with trans tune. To install you need to buy tune and brake Is more ,well worth it. They sell you or loan you a pass tru tool. You down load your info , send to them , they send you the engine and trans tunes , load them with the pass tru tool. If you buy tool can remove tune and put back to stock tune. Is not cheap, but if you keep your truck worth it

I have the stock setup saved on Forscan. So no issue there. I do like the fact that it only works in tow/haul mode. I currently use mine for work commute and occasionally towing my 5th wheel camper. Does the truck still do downshifting when in tow/haul?? After a 7000 mile round trip with the camper in tow, and several passes over the Rocky Mountains the truck preformed very well. The only thing lacking was an engine/exhaust brake while going down hill. The black hills and Custer park are just stunning!!!!

The down shifting the same , and the trans tune use all the gears.
