Fuel-It S55 BMW (CPI) Charge Pipe Injection KitAdvancements of S55 flash tuning and JB4 back end flash maps have removed the software fuel limits but created a new limiting factor, high fuel pressure pump volume. With higher boost targets and E85 fuel mixtures, the high pressure pump is not able to keep up with demand resulting in fuel pressure drops that trigger engine misfires, stuttering, and limit your overall performance. The Fuel IT S55 CPI kit addresses this limitation by adding extra fuel
Advancements of S55 flash tuning and JB4 back-end flash maps have removed the software fuel limits but created a new limiting factor, high fuel pressure pump volume. With higher boost targets and E85 fuel mixtures, the high-pressure pump is not able to keep up with demand resulting in fuel pressure drops that trigger engine misfires, stuttering, and limit your overall performance.
The Fuel-IT S55 CPI kit addresses this limitation by adding extra fuel injectors in the charge pipe to supplement fuel volume and take stress off the high fuel pressure system. Connected to the low fuel pressure system using high-quality plug and play AN lines and included fittings it allows fuel to be injected into the engine directly raising the overall fueling limit. Includes CNC machined couplers that screw into charge pipes with a 1/8" NPT bung. For those equipped with a JB4, the FSB controller is used giving the JB4 full dynamic mapping control and safety.

I love these pillows
Size: Queen (Pack of 2)
These are so comfy. I love them. They have made my life so much better.
I have really bad insomnia. I was also getting neck pains from my old pillows.
These are just the best for sitting up and sleeping. I can not tell you how much these changed my life.
They are worth a shot if you are looking for something.
10 out of 10.

Pillows not exactly down..
Size: Queen (Pack of 2)
I just got the pillows the tag say 80% polyester and 20% inner filling and 70% down and 20 % feather + ? Outer filling.. which is not what is advertised in the title. However AI indicated most pillows are constructed with two layers because of it is all dow it will be flat ... anyway the pillows will be tested after tomorrow as they recommend to leave it for one day before using it..

Great for side sleepers
It always seems hard to find the perfect pillow when you’re a side-sleeper. This one is great. It comes compressed so you will want to allow some time for it to fully fluff back up. The cover is soft and smooth. I love that it isn’t overstuffed. It provides gentle support and a lot of comfort. I was worried it may be too warm since it is polyester, but it is very breathable and I have not had any issues with feeling overly warm on it. It fits a standard size pillow case. It’s not overly stuffed like some other pillows I’ve tried that were specifically for side-sleepers. I think this world be a great pillow for any sleeping position, really. I wasn’t expecting to love a pillow this affordable, but it gets the job done and I get a good night of sleep. I’ll be purchasing some more for our guest room.
