Finally got a chance to tow a little with my GDE installed. Kind of hate to call it a "tune" but it probably does a lot without being noticeable. I keep thinking a "tune" should make it some kind of 'fire-breathing' dragster.

My impressions about fuel mileage changes is they are minimal. Mostly I got about about 24 mpg overall. Now I am about 25 mpg overall UNLOADED and not towing. You will see higher mileage if you keep the speeds under 70 mpg. Unloaded I think the GDE is good for about an 8% fuel mileage increase.

I just towed for 1,000 miles but not heavy. Smaller open trailer with just a quad and tools on it. Mostly on the interstate, I kept my speeds down a bit to try and get maybe get better-than-normal fuel mileage.

These were my speeds over that time and I got 22.5 mpg towing. Before the GDE I got about the same. Little to no change in towing fuel mileage.

I like the change in cruise control. Seems it will slow down a bit more on hills and speed up a bit more downhill. It's almost like an educated foot for better fuel mileage. What I also liked was what I think is a more gentle downshift without the abrupt change being so noticeable.

Also saw a lowered transmission temperature. Mine mostly runs real hot. This kind of tow would show me temperatures in the 210 to 220 *'F range at 75 mph. Although a bit lower in ambient temperature than normal , the transmission temperature is much lower than normal. I like that.


Have never noticed a change in power. My truck always ran well. It still does. You will not end up with a dragster.

There has been one regeneration during the 2,000 mile GDE usage. Also hope the EGR system is shut off. That's not something I can see or want to try to see.

Is it worth the $800 and installation issues? Those two things might be the only negatives.

Thanks for the write up Cap. Nice to read a review based on observations and not an advertisement.

Good consideration. Quite often advertising hype or maybe a highly-supportive sponsor dictates the review. I did the review because, to me, $800 is a lot of money and I expected some changes for the positive. Not sure there were many and none were dramatic. Then, on reflection, that just might be a good thing as the engine is not stressed and does seem to run at least as well as before or better.

Said before and will say again now, the EGR shut-off is a big deal to me. Crazy that's not something I can see and quantify unless I tore it apart, cleaned things up and then looked thousands of miles later.

That's not going to happen by me.

aren't all personal reviews based on observations?
Ha. Maybe I should've clarified- unbiased and even keel observations. Caught up neither by the love nor hatred of a particular product.

That's what reviews are. As a potential customer, you have to read them all and then make your decision. I don't know of many customers that read one review and make a purchase. I sure don't..

Me too. Looking at this tune as well.

Did you notice with the GDE , any pick up in the throttled delay? Some say it goes away with this tune?
Did you gain any HP'?

Never had a throttle delay. Might be because I'm too stupid to notice one. Might be that my very early, near first, model did not have any delay from the start.

After thousands of miles with GDE my overall normal operation is right at 27 mpg if I do not tow.

Take a look at your oil, if it's not pitch black after a thousand miles on fresh oil your egr is off; congratulations. 800$ probably well spent
