Re: green diesel engineering tune

It's magic. It is adjustable and it's german... I believe the sprint booster is a nice piece, but i really think this is a step above. I am really impressed. Solved the throttle lag. Makes this thing spin all fours, no problem.

What is the product? I've tried various googling alternate search strings for pedal box jeep grand cherokee, etc.

My main issue and interest level in this tune is to remove the lag. I have left turn into traffic as part of my morning commute and I dread it every day.

Re: green diesel engineering tune

DTE pedal box. It is a simple plug in. Eliminates throttle lag. Or you can get the sprint booster as well. Great reviews. The DTE is more tune able and $50 cheaper.

even with sport mode ON you feel the standard tune let's you down?

I've had a couple of weird electronic related issues w/ tune and dealer flashing it with latest PCM and TCM seem to remedy it. Time will tell but so far 550 miles and "Service 4wd System" along with tranny stuck in 8th has not returned. Previously I had the error intermittently (after 15k trouble free miles in the tune) and would recur every 130 miles or so. Prior issue was a MIL caused by extended periods between regen.

Re: green diesel engineering tune

It is a let down. I can't even imagine how i ever drove the thing stock... Use the sprint booster or pedal box with or without tune, you will be pleasantly surprised. Both of these seem to be great products. No throttle lag....

Wow that sounds pretty awful...and frequent. Did it just go away on its own or what did you have to do to fix it?

Re: green diesel engineering tune

This may have already been addressed but can someone explain exactly what the tune does with the EGR. I have 27k on my '15 SFU and today I threw my first code, 403/EGR. I have had the GDE tune installed since 18k and had zero problems prior to the tune. I was under the impression that the EGR was non functional with the tune so how could it have thrown a code? I did notice a couple of times when I had Torque running that the EGR appeared to be active showing .1% open but later returned to zero. Have not been to the dealer since the tune so overwriting could not be an issue. I reset the code to see if it will happen again.

Let us know what you find out from GDE and/or the dealer. I'm curious how this would be fixed and what the issue is. And cost to fix...

The EGR isn't 100% turned off with the tune. It's 99.9% off. It's still used as a relief valve for the turbo. Otherwise, the valve is electronically shut

Absolutely, would be very interested to learn more about what may have happened.

The EGR is commanded closed all the time with the tune. We did not turn off all the potential electrical faults like open/closed circuit or h-bridge malfunction. Your egr seems to have an internal fault. Give us a call and we can shut it down if not wanting the dealer to replace the valve. GDE
