Wondering how much power your car really has? Whether you’re looking to remap your vehicle or just satisfy your curiosity, checking your BHP (Brake Horsepower) is a great place to start.
At Pro Remapping, we’re often asked, “Can I check my BHP with just a registration plate?” The answer is yes – and in this post, we’ll show you how it works, what affects it, and why it matters if you’re thinking about a performance upgrade like a Stage 1 ECU remap.
⚙️ What is BHP?
BHP, or Brake Horsepower, is the measure of your car’s engine power before losses like friction and drivetrain resistance. It tells you how much “usable” power the engine produces. It’s different from wheel horsepower, which is measured at the wheels on a rolling road.
Understanding BHP is important not just for car enthusiasts, but for anyone considering performance tuning, towing capability, or even fuel economy improvements. The higher the BHP, the more capable the engine is at delivering power efficiently.
How to Check BHP by Registration Plate
Most vehicles in the UK are listed in public databases that include technical data like engine size, BHP, and emissions. Using your registration number, tools like our Remap Calculator can pull this data instantly.
Here’s how to do it:
- Go to our Remap Calculator
- Enter your vehicle registration
- See your stock BHP, estimated torque, and the performance gains available with a remap

Why BHP Figures Vary
Even among the same model and year, BHP can differ. Manufacturers release different engine versions – for example, a VW Golf 1.6 TDI might come with 90bhp, 105bhp, or 115bhp depending on the variant.
That’s why registration-based lookups are more accurate than simply searching by model alone. We also run a VIN check if needed to confirm engine codes and compatibility before any tuning is done.
What Affects Your Actual BHP?
Even if your car was rated at 150bhp from the factory, real-world figures can drop due to:
- Engine wear over time
- Blocked filters (like DPF or air filters)
- Poor servicing or low-quality fuel
- Carbon build-up or ECU restrictions
That’s why it’s important to keep your engine clean and well-maintained if you want to retain or improve performance.
What Can You Do With This Info?
Once you know your BHP, you can make smarter decisions about remapping, maintenance, or upgrades. If you’re underwhelmed by the figures, a remap might give you that extra power you’re looking for – safely and legally.
It’s also handy for second-hand car buyers. If you’ve bought a car and aren’t sure which engine variant it is, this tool will confirm it for you in seconds.
What BHP Means for Remapping
Knowing your baseline BHP is key before any ECU remap. Our tools show you exactly how much extra power and torque you’ll gain with a safe, reliable Stage 1 tune.
For example:
- Ford Transit Custom 2.0 TDCi – Stock: 130bhp → Tuned: 180bhp
- BMW 320d – Stock: 163bhp → Tuned: 210bhp
- Vauxhall Insignia – Stock: 140bhp → Tuned: 185bhp
Each remap is tailored to your vehicle’s ECU and driving needs.
Real Example
A driver in Stafford came to us unsure which version of his Peugeot 308 he had. Using the reg, we confirmed the lower-output 1.6 diesel engine. We showed him the gains, booked him in for a same-day remap, and he left with a noticeable power boost and better fuel economy.
Why Use Pro Remapping?
We’ve helped thousands of drivers across Staffordshire and Cheshire get more out of their cars. We use tools like Autotuner and CMD Flash to extract safe power increases, always starting with a full BHP and diagnostic check.
