Putz-in around is so much more enjoyable now. I actually use a lot less pedal than before because it has more power and more power earlier. It requires less pedal to get moving and to speed up.

The answer to your second question is far more subjective. If I'm in a playful mood, it will beg you for more and is so much more fun to drive now. However, if I'm commuting, have passengers, talking on the phone, etc. it drives nice and smooth like the tune itself is factory. It certainly doesn't have any high strung nature to it. It's actually more reassuring to drive now because it does what I want it to do, instead of flooring the pedal and waiting for it to do something like before.

No fuel additives here either.

Thanks for the information. You sound like you are working for GDE. Everything you are telling us sounds great. $750.00 is a lot of change to shell out making a blind decision without any sort of money back guarantee. I think I almost have the wife convinced, but she's still skeptical since everywhere you turn there is another money scam in the good old USA.

Yeah, I realize that. I was truly skeptical that a tune or go between chip could result in enough benefit that I would have considered it worth the money. The moment I had to turn the AC on for the summer here, I was really sold.

Plus, I shouldn't have to worry anymore, or at least nearly as much, about the SRC failure or EGR/turbo coking. That's something a go between chip can't do.

As far as scam, these guys have been in business for a long time, are referenced out the a$$, and aren't really soliciting anyone.

I don't know anybody here on the forum, I am picking up my GC tomorrow and I've been reading everything I can about the Jeep and the engine for the last 2 months while it's being built. Anyway, what everyone is describing here, is simply a tuned turbo diesel motor.

That's what happens, it gets smoother, more powerful, and better economy if you stay out of the go pedal. VW's were no different. Just sayin' if that helps you, or sometimes more importantly the ol' lady, out at all.

Oh, and for what it's worth, I'm flying from CA to OR to get my Jeep and I'm taking a GDE ECM with me to swap out as soon as I take it off the lot I've had several diesel vehicles over the past 10 years or so and it only took one tune to hook me. Stock diesels are alright, but tuned they are that much better!

Amen Brother! Thanks for the reassurance. My wife is the hard sell. She likes the Jeep just the way it is. If the tune is exactly how all you describe it, then she will Love the Jeep and I won't be able to keep her out of it. Thanks everyone.

Re: green diesel engineering tune

If it weren't for the absence of a flash programmer, I'd be all over this tune. Tuning is no joke. It can make a big difference for just about any motor with a turbocharger--gas or diesel. I had an Audi with a 2.7T motor. I added an APR tune and it was night and day. Cheater boxes I think are indeed snake oil crap. However, you change the parameters for the turbo, like boost pressure, in addition to other changes and now you're talking. Lag disappears, torque curve flattens out after peaking. Fun stuff.

I wouldn't call tuning boxes snake oil. I put them behind custom mapping, but they have their uses too. On the VW TDI's there was a tuning box that made just as much power as the best custom flashes could with similar amounts of smoke. I never drove one, but suspect that the everyday driving experience with a full software flash must be nicer than a plug in "fooler" box.

Please report how the new ride is with the Hot Tune installed. How are you getting your new Jeep on a Sunday?

Re: green diesel engineering tune

The MPG improvement over combined driving is tempting. But let's not kid ourselves, this tune isn't about MPG its about SPG. The Diesel never penned well on paper for efficiency for those that don't tow. I wanted a Diesel for the torque and sound.

I don't know about that, I like better fuel mileage. It's the second thing Green Diesel Engineering talks about in there results printout. I want fuel mileage a close 2nd on my list right after torque and sound is good.

Do the math on earning $750 back in fuel savings. For me a generous 26 to 31 MPG combined on 15,000 miles a year is $250 in savings per year. Hopefully there isn't any more issues with the JGC. I haven't decided if this will be my 8 year ride.

Totally agree. I was surprised when my I found out my EcoDiesel got worse overall fuel economy for my driving usage than the heavy old V8 gasser sedan I was driving prior to that. I'm happy with my EcoDiesel because I wanted to own a diesel truck. I probably would *not* be happy had I bought it hoping it would somehow save me money in fuel.

However, *if* you're planning to keep your Jeep for the long term, the GDE tune's EGR/SCR tweaks may end up paying for the tune through preventing damage/wear/clogging that would result in post-warranty issues. Hard to say for sure at this point, but it's definitely a strong weight in the "pro" column for me.
