Thank You and If I need anything else gauge wise or another like that, I will definitely get it through Prosport. ### ⭐ Doesn’t Work *by M***N on January 15, 2023* Installed this gauge and calibrated the sensor twice outside the exhaust twice. It reads correct at idle but at full throttle, it goes down to 10.0 and stays there and I know the car is not running that rich. It’s an expensive gauge so really annoying it doesn’t work. ## Frequently Bought Together - Prosport Gauges EVO Wideband Red & Blue 52mm Digital Air Fuel Ratio Kit - Oil Pressure Gauge- EVO Series Red and Blue Digital 52mm (2 1/16") --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/7972980-prosport-evo-wideband-digital-air-fuel-ratio-gauge-52mm-2](https://www.desertcart.vu/products/7972980-prosport-evo-wideband-digital-air-fuel-ratio-gauge-52mm-2) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-07*
