Delicious Tuning -  Mk2 Flex Fuel kit is a complete seamless solution for your EcuTek, that any EcuTek Master Tuner can tune. It features all the same functionality as the discontinued Cobb's standard flex fuel kit, but with a few extra features and functionality.

The Mk2 can use O2 sensor inputs (built to order), to get the ethanol content or fuel pressure signals to the ECU. Please select which input you desire from the drop down menu.

With the Bluetooth feature, you can now monitor your fuel pressure, fuel temp for starting, as well as ethanol content. These parameters can also be displayed via the Accessport display.

Flex Fuel Diagnostic System (FFDS) that can detect electrical opens, electrical shorts, sensor failures or even too much water within the fuel.   The fault detection can diagnose an open in the electrical system, short, bad ethanol sensor, too much water in the fuel system, and fuel pressure loss. 

Fuel Presure System (FPS) will display and dynamically control injector opening time to finely adjust fueling and open in the event of fuel pressure loss.

The included Stumble Fix Kit eliminates the infamous 2800 to 3200 RPM stumble that occurs on 08-16 STi's by eliminating fuel pressure regulator buffeting, through using a more stable vacuum source and specific tuning strategies.  

Delicious Tuning FlexFuel BlueTooth Kit includes:

- Delicious Tuning FlexFuel Ethanol Content Analyzer with Integrated BlueTooth
- Delicious Tuning Smart Phone Applications (Android or iPhone Compatible)
- Delicious Tuning Hand Assembled and Pressure Tested Fuel Lines
- Delicious Tuning Mounting Bracket and Hardware

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.

It works! Quality pillow.
Size: Standard (1 Count), Color: Original White (Cooling)
This does actually provide a cooling effect, and it's very comfortable! The accompanying literature is helpful too. I believe this to be a quality pillow for the price.

Most comfortable pillow I’ve ever slept on
Size: Queen (1 Count), Color: Crescent White(cooling)
This is the most comfortable pillow I have ever slept on. It doesn't mash down like other pillows. Cradles my neck perfectly plus it’s cool. I broke my neck a couple of years ago and this pillow feels very good and comfortable. Definitely recommend to everyone. Ive used it since May and it’s retained its shape.

Smell
Size: Queen (2 Count), Color: Original White (Cooling)
The fact that there are not more comments on the smell of these pillows has me worried about some of yall. Listen, I LOVE the weight, and the firmness, it’s perfect for that. However, these pillows are RANK. They have a very strong mildew-ish smell that lingers. I took the outer cover off and washed it and let the pillow air out for a few days, the smell is still very strong when you press your face against it, which one does because it is in fact designed for that purpose. It smells so bad. It’s nauseating. I can smell it through two pillowcases and blanket that I threw on top of them hoping an extra layer would trap the smell. I’ll bake them in the Texas sun tomorrow and hope that helps, because otherwise these are the perfect pillows for someone who wants to feel like they are hugging a torso but can’t stand the sound/feel of someone else breathing. I don’t know…4 stars, if the smell goes away I’ll come back. Update: many many days later. Either they don’t really smell anymore or I got use to it. They’ve held their firmness and shape well. I like them.
