TO DETERMINE WHICH PEAK & HOLD YOU NEED
- Grab a multi-meter and select Ohms 200
- Touch the positive and negative leads of multi-meter together to measure resistance (record this number...i.e. measured 0.3)
- Then take the positive and negative leads from multi-meter and put on each terminal of the injector. Doesn't matter the order. Record this measurement
- Take the ohms measurement from Step 3 and then subtract the number you got in Step 2 (i.e. Step 3 4.8ohms - Step 2 0.3ohms = Total 4.5ohms)
High Impedance Injectors - Above 7ohms - No Peak and Hold Boxes are needed.
Peak and Hold 2A - 3ohms to 7ohms (Bosch 160lb/hr).
Peak and Hold 4A - Below 3ohms to 1.5ohms.
Peak and Hold 8A - Below 1.5ohms (Billet Atomizer*).
All low impedance Billet Atomizer Injectors manufactured after Nov. 2012 require 8A regardless of measured resistance.
*Billet Atomizer Injectors - Anything prior to serial # C300**** should only use the 4A/1A. This only applies to injectors manufactured prior to Nov. 2012.

Perfect for me and my kids
KOORUI 27 Inch Curved Monitor and I am extremely satisfied with its performance. This monitor is perfect for both gaming and desktop use, delivering an immersive and visually stunning experience.
First and foremost, the 27-inch curved display is a game-changer. The curved design enhances the viewing experience, making it feel more engaging and immersive. Whether I'm gaming or working on desktop tasks, the curved screen pulls me into the action and provides a wider field of view.
The FHD 1080P resolution ensures crisp and clear visuals, allowing me to enjoy games and media with stunning detail. The colors are vibrant and accurate, and the overall picture quality is impressive. I can easily spot even the smallest details in games, giving me a competitive edge.
With a 75Hz refresh rate, the monitor delivers smooth and fluid visuals, minimizing motion blur and ensuring an enjoyable gaming experience. Whether I'm playing fast-paced action games or watching videos, the smoothness of the display adds to the overall immersion.
The monitor offers multiple connectivity options, including HDMI and VGA, allowing for easy connection to various devices. I appreciate the flexibility this provides, as I can connect my gaming console, PC, or other devices without any hassle.
One feature that I particularly value is the tilt adjustability. The ability to tilt the monitor allows me to find the perfect viewing angle for maximum comfort, reducing strain on my neck and eyes during long gaming or work sessions.
Another important aspect of this monitor is the eye care technology. The 1800R curvature and eye care features help reduce eye strain and fatigue, even during extended usage. This is a crucial consideration for me, as I spend a significant amount of time in front of the screen.
The sleek black design of the monitor adds a touch of elegance to my setup. It blends seamlessly with my gaming or office environment and enhances the overall aesthetics.
In terms of value for money, the KOORUI 27 Inch Curved Monitor is an excellent choice. It offers a combination of immersive visuals, smooth performance, and eye care features at an affordable price point.
Overall, I highly recommend the KOORUI 27 Inch Curved Monitor for both gaming and desktop use. Its curved display, FHD resolution, smooth refresh rate, and eye care features make it a standout choice. Whether you're a gamer or someone who spends hours working on a desktop, this monitor will undoubtedly enhance your experience."

Excent price / quality relation
I had some good expectations about this screen and they were accomplished. The quality is good, it has few modes in its configuration for eye saving or performance.

It's alright
Performs well on high graphics for gaming. My only complaint is that this has a lot of backlighting. The screen is very bright and not very saturated. I also don't like that you can't adjust the screen height. But other than that, a decent curved monitor.

Game changer! Literally
I use this monitor for work and I don’t need to turn my face to see the edge of the screen. Absolutely love it! Bright enough but not too much to bother my sight! Nice color, monitor not too heavy but still good quality. Lots of value in this purchase! Highly recommend to my colleagues and friends!
