Results in torque and power gains across the full operating rpm range, starting right off idle and marching to the shift point in each gear. Derringer is dyno calibrated to use multiple data inputs such as throttle position, rpm, vehicle speed, AFR, knock, coolant temperature, and EGT, just like your engines ECM. It actively and safely optimizes calibrations in real-time thanks to its OBD-II connectivity. No competitive tuner does that. Derringer has 6 levels, adjustable on-the-fly using the iDash. Level 6 produces best-in-class performance. Level 3 is designed for work use and has a great mid-range feel. When running Level 3 with a loaded truck and/or pulling a trailer, your on-ramp merging speeds and passing times are greatly improved. The electronics are enclosed in a compact housing which is easily concealed and communicates with other Banks devices such as our iDash DataMonster, iDash SuperGauge, and PedalMonster throttle booster. The Derringer connects in line with your trucks engine sensors. But unlike other tuners, it also connects to the vehicles OBD-II diagnostic bus. ActiveSafety health monitoring circuitry keeps an eye on the vehicle and the module itself. It checks its health 100 times a second. If it detects an issue, the Derringer instantly bypasses itself, sets a device diagnostic code, and seamlessly returns the truck to stock power. Plus, Derringers special coolant temp monitoring prevents power addition when the engine is too cold or overheated. The Derringer also auto-adjusts power if knock occurs due to bad fuel. Maximum safe power is all automatic with a Derringer - you just choose your preferred power level and enjoy the ride.This Part Fits:

Wonderful
Super comfy and easy on and off, yet stylish imo! I could walk miles in these as a 56 yo and have worn them for three years! I hope they never stop making them. The only tweek I would suggest is to cover the footbed with leather or suede not cloth so they would last longer!

Lovely sandals!
I highly recommend!
These are so comfortable! Right out of the box, they can be worn all day. The velcro-adjustable straps are great for making for a perfect fit. The aren't clunky to wear, even though they appear to be. They're super cute, in my opinion. The sock liner is textile, so feet feel good all day, not slimy, like leather and suede can sometimes make feet feel if socks aren't worn.

Cute and Comfortable
Size: 10, Color: Black
This is my second pair. I bought the sand color at my local Macy's. I got their last pair. I have issues with back pain and ankle swelling and pain. These are so comfortable I had to get them in Black. The adjustable straps are great. My feet are a little bit wider because of the swelling issues. So if you have very narrow feet these might be a little big. You might want to go down a half a size. But otherwise I wear a size 10 and they fit perfectly. I don't think the picture does the color justice. The black almost looks like velvet, it's very deep and rich. I wore them out today for the first time and got lots of compliments. The footbed is very comfortable with the memory foam. Lots of support. I noticed my back and ankle pain is much better wearing these. I've never owned UGG before. If these hold up really well and continue to stay comfortable, I will be purchasing other styles for fall and winter.
