“I would like to start by saying that the company has amazing customer service. Which is something very difficult to find in my opinion especially with the diagnostic side of the industry. Every question I had they were quick to answer the phone and help me step by step. The Proformance link tool is easy to set up, easy to update. And even easier to use. I love how I am able to monitor my live data during a regeneration with the vehicle stopped or driving down the road. Very easy and clear information in the fault codes with significantly better troubleshooting procedures compared to some of the other tools I’ve used. The other functions they have Incorporated into the tool would make it ideal for even a shop technician to use. I Belive all around function, customer support and price point. This is a top tier tool on the market.”

“I’ve been using the Proformance Link scanner for a while now, and it’s worth every penny. As an over-the-road truck driver, DPF issues used to cost me time and money. This tool lets me initiate parked DPF regeneration whenever needed, reset the DPF carbon load, and diagnose trouble codes fast. It reads current faults, shows clear live data (pressure, temp,), and lets me clear codes right after repairs.”

“ProFormance Diagnostics checks all the boxes. As an owner operator of a one truck operation my Peterbilt always needs to be up and running. I don't like surprises and when something comes up I like to get it repaired where I want. The ProFormance Link gives me real time data, informing me of all the right information. Having an emissions tractor, I need what they deliver. Thanks Proformance!”

“As a Volvo truck driver, I’ve used several diagnostic tools, and this one stands out for its speed, accuracy, and practical functions. It helps identify fault codes clearly, saves troubleshooting time, and supports key service tasks that matter on the road. The interface is straightforward, and the system feels built by people who understand real trucking needs. For owner-operators or fleet drivers working on Volvo trucks, this tool is a solid investment.”

“Really impressed with Proformance Diagnostics. The device is small but powerful. It easily reads and clears codes, and also supports advanced functions like DPF regen, DPF reset, and SCR efficiency checks. Fast, accurate, and very helpful for diagnostics.”
