Another vote here for the Timber Groves. Oustanding quality, easy install and great customer service.

I did the AEM emissions update a couple of weeks ago. Happy to report the truck is performing well and I''m satisfied. Haven't put enough miles on it to evaluate MPG but it seems to have lost a couple. I will never know the MPG factor because I'm putting my SFT ECU & TCU tunes back in.

TC, The dealer is required by law to install the AEM but the owner is not. The owner can "opt out". 26. How do I get out of the Class Action Agreement? If you do not want to receive the benefits provided by the Class Action Agreement, and you want to retain the right to sue the Defendants...

You repair invoice should show any recall, emissions, safety, etc flashes

TC, I never gave mine a chance to get 30pg. I leveled it, etc right away, before I made any long highway runs. Last week I de-tuned it and got the AEM latest flash. Truck runs great, no lag, etc. I won't have an after AEM mpg because I'm putting the tune back in as soon as that update arrives..

City 18-19. Hiway 23-24 @ 65-70 mph, 20-21 @ 70+ mph 2016 Eco, ECU & TCU tuned, no air dam, leveled, 10 ply tires, always 600+ lbs load incl shell

I bought one but haven't tried it yet. It gets great reviews. Hopefully it will perform as advertised.

They did my 2016 on May 5. I'm happy to report it seems to be performing and shifting as advertised. I've been driving it stock to see if there are any problems like what have been reported. So far none. I will be putting my SFT ECU & TCU tunes back in play as soon as I get the AEM updated tune.

Good decision :)

Yes, If GDE isn't already he will have an approved tune. There's no reason not to believe what they are saying about the new tune, Kieth has a good reputation and apparently some good engineers/tune experts available. What bothers me a bit is GDE has always said it is important to turn off the...

Caveman, Here's what I've learned. The original GDE tune had long intervals between regens and espoused that it was a cleaner tune (less soot production). However, it has been reported that GDE's cleaner tune came at a cost of high temps. The SFT tune, like the factory tune, has more frequent...

The SFT tune operates the "engine/exhaust" (actually it is turbo braking) braking automatically when you are in tow-haul and above 2000 rpms. To keep it above 2000 rpms you merely downshift to another gear. I'm not sure how it activates in the other tunes.

I have the SFT handheld tuner and I believe HD Diesel is using the same device. I recently had the AEM emissions update and prior to going to the dealer I used the handheld to return to the stock tune in my ECU and TCU. After the dealer's emissions flash I reinstalled my SFT tunes - easy...

The DEF tank has a membrane inside. If it dries out the tank is toast

My 16 was completed last week

I agree. SFT was working on extending the regen interval. I haven't anything recently. Don't know if it's a backburner item, a difficult thing or what.

Yes. You need a Windows computer to download and upload. Once you have the tunes it's Easy Peasy with the OBD2 handheld touchscreen tuner

SFT does everything it's advertised to do. I've had both GDE and SFT. GDE had longer regen intervals, a big plus but at some cost (higher temps). SFT gets the same mileage and more power off the line, better towing and runs cooler. SFT customer service is outstanding. If you get the SFT TCU...

I find regens vary a lot depending on temps and type of driving (local or hiway) I started tracking with my Edge and started with my latest SFT tunes. SFT pretty much follows OEM regen philosophy. Here's my chart:

Gotcha - I had the hot tune - no deleting
