I found a used GDE Supertune. Every aspect of the tune is superior to SFT (drivability, mpg, power, etc). Additionally, I tried out EcoUSA for a time and no matter what you want to say about Randy, his tune is far superior to SFT (actually starts properly and doesn’t have erratic boost).
How did you get the GDE Supertune you found to work with your specific truck? I recently had to do a full delete due to mechanical issues and switched from the GDE stage one tune to the SFT tune and am unhappy with it as well. I still have the ECM with the old GDE hot tune on it but it only shut down the EGR, do you know of a way to update the GDE tune to stage 2?
