You get the same diagnostic capabilities that dealers use, right on your mobile device.

Yes. The Proformance membership includes one free VIN transfer per year. If you purchase a new vehicle, upgrade, or replace your current truck, you can transfer your membership without any additional cost once per 12-month cycle.

Here's the real cost savings from our Proformance users:

• Average dealer diagnostic: $475 per visit
• Time waiting for appointment: 2 to 3 days lost revenue ($2,000+ for most loads)
• Average forced regen at shop: $400 plus 4 hours downtime
• One misdiagnosed problem: $1,500+ in unnecessary parts

Our Proformance users report saving an average of $3,200 their first year. That's real data from real truckers.

With Proformance, you diagnose immediately, fix only what's actually broken, and keep rolling. One avoided breakdown or tow bill (averaging $1,200) pays for your membership twice over.

Unlike basic code readers, Proformance provides true dealer-level access with the ability to run commands like forced regens, SCR regens, reset DPF and more.

Your Proformance membership covers ALL engine brands with one tool (not just one manufacturer), includes continuous updates as truck technology changes, stores all your data securely in the cloud, and works perfectly on your existing phone or tablet. No expensive laptop needed.

Your Proformance membership continues smoothly, keeping all your features, data, and benefits active. You can choose annual renewal or switch to monthly payments after year one.

Your diagnostic history stays saved forever in the cloud, even if you pause your membership. The hardware remains yours, and you can reactivate anytime to access all your historical data.

Because Proformance delivers on its promise: total control over your maintenance, 24/7.

Our users never worry about surprise breakdowns, expensive diagnostic fees, or being sold unnecessary repairs. When you're broken down at 2 AM, you'll understand why so many drivers won't run without Proformance.

With lifetime hardware protection, if your adapter ever fails while you're an active member, we'll replace it free. That's our commitment to keeping you on the road.
