John speaks the truth below! I went with gde originally for the engine tune, I could not justify the transmission tune as there were no reviews out there that gave any sort of description except for, it's great, or wow. Was not convinced to drop $600 for that. And that's what drove me to originally developed the SFT transmission tune.
Fast forward a few months, in February I released the OBD2 flash ability for the engine. obviously people were waiting a long time for this and here I am coming from nowhere all of a sudden tuning the EcoDiesel engine via OBD2 yet these other companies could not for so long. After purchasing the gde super tune and being very disappointed that drove me to develop my own for the EcoDiesel, stage 1 with all the emissions intact, and Stage 2 fully deleted off road.
With the gde hot tune, speaking from personal experience I really have a neutral response but positive when it comes to MPG. I was happy with the EGR being shut off and the increase of MPG. Being able to set the cruise control At a lower speed and all that was great as well. I was very disappointed with the super tune, I had to barely press the throttle otherwise it was going to smoke like a chimney. Absolutely no noticeable increase in horsepower but it did make my engine sound like it was pre- detonating when it was not supposed to.
Working the clock basically 24/7 for weeks, I partnered with an engineering company to develop to Stage 1 and Stage 2 engine tunes. There's hardly any smoke with the fully deleted tune. There's absolutely no throttle lag after 800 RPMs. The only throttle lag experience is from the actual turbo having school up. Stock there's a 2.8 second delay programmed in there from the factory. We keep all the safety measures in place, the highest torque output is 712 NM, this is safe for the transmission, others are well over 800 NM. And that is fine for them, they will even advise against using the other tunes. We highly recommend hours because we want to keep things safe, within check and increase the longevity of your engine and transmission.
I did not get any money back from gde, I could barely get them to respond to an email after asking for the super tune and if I did things correctly. at this point, the company itself and disappointed in the ownership as for the quality of their tunes, I would recommend the gde hot tune to somebody with minor mechanical know how to remove the airbox and install the ECU.
I will say for Father's day Sofa King tuned LLC is giving 20% off to everything in the store. That means you can get an engine and transmission tune shipped priority 2 - 3 day shipping for only $720! All tunes are OBD2. You just need your Windows computer and the vehicle. Turn the key on and off when instructed and that's about it. Get phenomenal increases in MPG, drivability, longevity. Enjoy your new vehicle for a long time and less time spent at the pump fueling up
