Mine is stock except for the tune. It's hard to say how a CAI or exhaust might affect things. All things equal, there will be some variance in actual results just because there are variances among all stock engines, but the tune is exactly the same.

Re: green diesel engineering tune

Thanks for the review dsears00. My GDE ecu arrives tomorrow. Unfortunately I don't get my GC till Sunday.

I gotta install the ecu, an oil catch can, an AFE intake, get a clearbra installed, and then get to drive it about 2000 miles visiting family and vacationing up and down the west coast. Good times ahead!

Re: green diesel engineering tune

Another question for GDE.

Did you adjust when the system tries to run a regen with the tune.

With my reader and some of the forum posters on there I have a readout of usually 9.4 - 100% for the DPF. It seems to try to run a regen when the value is over 60%. Was this shifted up for the tune to help reduce the number of regens or is it just engine tuning that is making the regens happen less often or both? If it was adjusted what point does it try to regen now?

Thanks for all the clarifications.

The power increase is really nice and gives the GC a lot more grunt without being ridiculous. It was pretty stout stock for a 5,500 lbs. vehicle, but you could tell it was just enough and nothing more. With the tune installed, it feels much stronger throughout and never struggles.
0-60 only .8 faster is somewhat disappointing. Not sure where I read it, but I thought the expectation was closer to 1.5 seconds faster unless at high altitude. .8 makes sense given the HP and Torque numbers I guess, but was (always!) hoping for more.

Some of your questions are answered here: Green Diesel Engineering

Also search the ram1500diesel forums. Lots of information there in the Green Diesel and Tuning sub forums.

Re: green diesel engineering tune

Thanks Wiz,
I had gone through the GDE site and read it before, for some reason it didn't connect when the question popped in my head.

Looks like they use both methods and the regen start is 80%.

I have never bought a tune for a car but this looks really nice. It gets really annoying that the constant regens end up costing 2-4 mpg depending on when it decides to run.

No problem, and I agree with you. I like the GDE tune, looks like they've done everything the "right" way to both improve engine longevity while getting the most out of it (power and MPG!) at the same time.

With the stock tune I too can tell when a regen is occurring based on MPGs. Suddenly getting good mileage becomes much more difficult while it does the DPF clean up. I'm guessing a decent portion of the GDE improvement is coming from simply not needing to regen as often. Though I'm certain there's more to it as well.

Poke around on the RAM1500Diesel forums as well, there are a lot more RAM Ecodiesels with the GDE tune probably because there are a lot more of them on the road. Plenty of good reviews and information "over there". I haven't heard anything bad about the GDE tune yet...well, except for the whole warranty issue. Nothing they can do about that.

Re: green diesel engineering tune

I may have missed it - but would like for GDE to tell me: will this void my warranty and service contract?

That's not really up to GDE. :-) But if your engine blows up - probably even your tranny or any other driveline component - while using it, you can bet FCA is gonna get out of fixing it under warranty if they find out about the tune. They can't be expected to support or be responsible for damage caused by a tune over which they had no control.

Re: green diesel engineering tune

I know the GDE system seems better with the improvements they make, but does the Banks Bullet seem like a safer option until the warranty is up? It seems like it could be removed with very little "evidence".

Re: green diesel engineering tune

The banks system is just a fooler box and complete junk. Many of those that have tried it ended up with fault codes due to a rich fuel mixture.

We prefer to tune the right way or not do it at all.
