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 engine's 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 truck's engine sensors. But unlike other tuners, it also connects to the vehicle's 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, Derringer's 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:

It really does the job!
Size: 8 Oz
This stuff actually works really well. It brought all my plastic back to life. And although I don't think it's designed to use on metal my toolbox is black and it looked faded and I did the toolbox with it and it looks brand new now. There's a die in this product that makes it last longer than most other products I believe. And if your plastics are really bad like some of mine were give it to treatments and you'll be amazed. You have to let it dry for a while it will be sticky depending on the climate for a day or so but it's pretty much dry it won't you know smudge or anything but it just feels sticky to the touch for a day or two. I've been through the car wash a few times since I treated it and it didn't hurt that new finished.
I do recommend this product.

Excellent results, easy to use, impressed!
Size: 8 Oz, Size: 8 Oz
I used the glide coat ceramic sponge applicators (it’s what I had) and the absorption was perfect. Application on trim pieces was super easy. Had to get a little particular around my mirrors and window trim (I didn’t tape, oops) I used 4-5 throwaway microfiber towels to wipe excess. Super pleased with 1st coat, may go back for seconds on my tonneau. I left each section to cure for about 7 minutes then wiped with towel. Leaves a nice matte finish that pulls out the sparkles in my Raptor trim. No sticky residue leftover.

Very good but over priced!
Size: 8 Oz, Size: 8 Oz
Great product and works very well. I was disappointed because of the high price and the small size bottle. But other than that it’s a very good product and makes my work van look clean, shiny clean. My van is white, but it was easy to clean it if I missed up. Good but over priced!

Super good
Size: 4 oz Kit, Size: 4 oz Kit
Super easy to use and seems to dry quickly. I think it’s a great value for the price. I can’t say how long the results last for but the process is easy enough and the results are good enough that I’d be down for doing it every couple months. It dries black and made my trim look brand new. Honestly the hardest part was just taping around the side mirrors. You should definitely get this if you’re on the fence about it.
