Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM's Wideband Controllers with X-Digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning. Deadtime is the delay between when exhaust gas composition changes and when that change is reported by the O2 sensor. While flow of exhaust gases can affect deadtime, it is not the only source. Often, the sensing element’s response to the gas is the largest contributor to deadtime.When tuning an engine using wideband AFR feedback control, deadtime affects the data you are looking at because it is reported in a different operating location than when it occurred. This means whatever changes you make to the base fueling will likely be in the wrong timeframe. This can be particularly dangerous to high cylinder pressure applications, and EFI systems that use feedback control.

Great feel, great fit, great value! Not great if you need shoes that breathe well...
Size: 10, Color: Brown
What did I notice about these shoes as a Cole Haan junkie? I was looking for some "cheapies" that were somewhat close to Haan's comfort. Tried several and these are by far the closest thing! So comfortable! These shoes fit according to size- and it was sad when I had to take out the insoles that came with these for my arch support ones- the insoles that came with the Bruno's are amazing. They are stylish and seem well built but I've only been wearing them for a couple of weeks. They get 4 stars because of a few things but overall a GREAT value for money! "Downsides" include fact that they breathe as well as we do underwater- not well at all! If you struggle with foot sweat- I'd look elsewhere. Also- the soles are super comfy but I get rocks, debris, and other things stuck in the deep grooves almost every time I walk off sidewalk. Just something to be ready to pick out regularly. Overall though- strong recommendation! Hopefully they don't rip out on me in a month! Will update if they do! :)

Perfect Blend of Comfort and Style
Size: 9, Color: Brown, Size: 9, Color: Brown
I recently purchased size 9 of these shoes, and they exceeded my expectations in every way! Here’s what I love about them: 1. Comfort: The moment I put them on, I noticed how soft and supportive they felt. The cushioning provides all-day comfort, making them perfect for long walks, workdays, or running errands. 2. Fit: The sizing is spot-on! I ordered my usual size, and they fit perfectly with no need to size up or down. There’s enough room for my toes to move without feeling too loose or tight. 3. Style: These shoes look even better in person. The design is sleek and versatile, making them easy to pair with both casual and semi-formal outfits. I’ve received several compliments already! 4. Durability: I put it on the day of purchase. After wearing them daily for a couple of days, they still look brand new. The stitching and material seem high-quality and built to last. 5. Value for Money: For the price, these shoes deliver exceptional value. You’re getting premium comfort and style without breaking the bank. Final Thoughts: If you’re looking for shoes that offer comfort, style, and durability, I highly recommend giving these a try. I’ll definitely be considering another pair in a different color soon! To conclude, I’m very happy for this purchase. Will definitely buy again.

Comfortable, Easy to Clean, and Held Up at Coachella
Size: 12, Color: White, Size: 12, Color: White
I’m really happy with this purchase. The shoes are very comfortable, and the product description is accurate. I followed the sizing recommendation based on my foot type and went one size up—they fit perfectly. I bought these for Coachella, and they definitely held up. I was on my feet all day, and they stayed comfortable the entire time. What impressed me most is how easy they were to keep clean. At the end of each day, I was able to wipe them down and maintain their whiteness without much effort. Once I got home, I gave them a deeper clean, and they honestly looked as good as new. Even the laces cleaned up easily. Now I’ve transitioned them into my regular work shoes, and they still look great. Overall, I’m very satisfied with this purchase and would definitely recommend them.
