HKS 4501-RA002 Fuel Cut Defencer

The HKS FCD is an electronic device developed to properly raise the factory fuel cut level on factory turbocharged vehicles. As modifications are made to optimize engine performance, the factory fuel cut is often triggered by higher boost levels which activate a fuel delivery cut-off as a failsafe procedure. Symptoms of fuel cut are hesitation, bogging, and/or illumination of diagnostic indicators.

The electronic signal from the FCD will raise the fuel cut level to accommodate for the additional boost without triggering fuel cut and/or an engine diagnostic light. The FCD installation is designed to be easily integrated with the VPC/F-CON or factory ECU harness.

Warning: Due to the characteristics of this product, higher than recommended or unsafe boost levels may be attained by the installation and use of the FCD. This may result in severe damage to the vehicles engine or other mechanical parts. We suggest a fuel delivery upgrade and consulting a trained technician before the purchase and use of the FCD.

No gimmick
It works very well. While it leaves the paint very slippery and shiny, the best part about this product is how easy it is to buff off. I have used many products and nothing comes off as easily as this. And it also smells incredible. Clay bar beforehand is essential to make buffing it off effortless. Make sure you use the correct pad and use very little pressure or spreading it will be difficult.

Black 2009 Chevy Avlanche-Better the Second Day
Okay... Let me say this first and foremost, this is a decent product. Of Course Chemical Guys makes some extremely over -the-top claims. However, no product can do all the things that Chemical Guys claim their products can do. Regarding this product, Black Light DOES NOT remove scratches and swirl marks... I know Chemical Guys tell you it do, but it DOSE NOT, however it did blend and reduce the appearance of minor to moderate scratches and swirl marks... The product reduces them very well. I was pleasantly surprised by this so that was good... Now the shine.... At first I wasn't overly impressed by the shine it left, but then I went back about 2 hours later and did another pass with my microfiber towel and took at step back and was like hmmm, not bad.... The second day there was some dust from over night on my truck (Black 2009 Chevy Avalanche), I wiped the dust off and I was I couldn't believe it looked better the second day. Now you can't always take another persons word on the quality of the shine/gloss look because we all have our own perspective on what looks good. Now it wasn't hard to apply... I used an applicator....Put on and light to moderate coating.... I let it sit for about 45 minutes...(I got distracted with other things) the directions say 15-20 minutes... It was not hard work getting it off, but it took slight work, maybe because I left on for double the time.... Overall, this product is decent, I have only used it once on 04/05/18 and today is 04/06/18. We are expecting rain and snow tonight, lets see how it holds up after that... But over-all I will give it another shot when the weather breaks, but this time, I will add the Chemical Guys'16 Hybrid V7 Optical Select High Gloss Spray Sealant after and see what kind of shine/gloss it will leave.... I never read the 5 Star Reviews because its mostly people who work for the company or paid by the company to write... 2 star, 3 star and 4 star reviews; you can get a more of an honest picture of the product... I hope this feedback help.... I do like it after one use, and I will use it again after the weather breaks, then I will write another review to give an update on how it held up after snow and rain...next time, ill add a pic...

Paint isnt perfect at 12 years old but WOW!
As advertised and reviewed. Did the application with a Chem Guys applicator 6 pack purchased here in the AM when it was 70 degrees, no sun. It went on easy, waited 15 mins, it came off easy. Beautiful glossy shine on my black Model S.
