Us Californians are limited.I'm not particularly satisfied on the way GDE has handled their shutdown, but they do (did) offer a superior product. I bought my GDE tune and installed on my Ram at 1,000 miles. I have SFT in my wife's Jeep Eco, I picked picked up MR tuning for my truck thinking a little extra power would be nice. If there is more power on the other tunes I can't feel it. Torque Pro app puts the GDE hot tune and MR Tuning +40HP tune within 5hp and 10 ft lbs tq of one another.
But the reduced regens and better warm-up and other "extras" of the GDE make it far superior to the alternatives. Of course if you haven't experienced GDE, you can go buy SFT and you'll probably think you've struck gold. You try to be "different" and ignore the "GDE Fanbase" here, but I've tried three different options and I feel like the SFT tune for my wife's Jeep was wasted money.
