A remap calculator — also called a vehicle gains lookup — lets a visitor pick their car and instantly see the BHP and torque gains a remap would deliver. It is one of the highest-converting features a remapping website can have, because it replaces vague promises with numbers tied to the customer's own vehicle. This guide walks through exactly how to add one to your site in 2026, the options available, and what it costs.
What a remap calculator actually does
At its simplest, a remap calculator takes three inputs — make, model and engine (or a UK registration) — and returns the typical Stage 1, Stage 2 and Stage 3 power and torque figures for that vehicle. The best tools then connect the result straight to a quote request, so a curious visitor becomes a named enquiry without filling in a long form.
That last part matters. A calculator that only shows numbers is a toy. A calculator wired to a quote workflow is a lead generator.
Your three options for adding one
1. Build it yourself
You can commission a developer to build a custom lookup backed by your own database of vehicles and gains. This gives you total control, but it is the slowest and most expensive route — you are responsible for sourcing the vehicle data, keeping it current, and maintaining the code. For most tuning businesses this is overkill. (We compare this properly in our guide on whether to build or buy a remap database.)
2. Use a generic form plugin
A handful of WordPress plugins offer basic "tuning calculators". They are cheap, but they rarely include real per-vehicle data, look generic, and almost never link to a proper quote system. Visitors can tell the difference.
3. Embed a ready-made vehicle gains lookup
The fastest route is to embed a purpose-built tool. Our vehicle gains lookup drops onto any existing website with a single snippet, comes pre-loaded with a full vehicle database you can edit, and includes the 3-click quote workflow out of the box. It works on WordPress, Wix, Squarespace or a custom site, with no rebuild required.
How to embed it — step by step
- Choose your layout and colours. Pick one of the available designs and set it to match your brand so the tool looks native to your site.
- Add the embed snippet. Paste a single line of code where you want the lookup to appear — a dedicated "Check your gains" page works best.
- Set your figures. The database is editable, so adjust the gains to match your own maps rather than relying on generic numbers.
- Connect your quote inbox. Decide where enquiries land and set up the quote templates so you can reply in seconds.
- Add the optional reg lookup. If you want customers to find their car by number plate, switch on the UK registration add-on.
Most businesses are live within 24 hours.
What it costs
A ready-made vehicle gains lookup with quote workflow costs around £17/month — far less than the developer time a custom build would consume, and with no data-maintenance burden. There is no setup fee and no contract.
Get it converting
Once it is live, link to it from your main navigation and your service pages, and use a clear call to action like "Check your car's gains". The easier it is to find, the more enquiries it produces.
