If you run a tuning business and want a vehicle gains lookup on your website, you face a classic decision: build your own remap database from scratch, or use a ready-made one. Both can work. This guide breaks down the real costs — time, data, money and maintenance — so you can choose with your eyes open.
What "building your own" really involves
A remap database is not just a web form. To build one that is actually useful, you need four things:
- Vehicle data. A structured list of makes, models, engines and their factory power figures — thousands of variants, kept current as new models launch.
- Gains data. Realistic Stage 1, 2 and 3 figures for each of those engines, based on credible tuning results.
- The software. A lookup interface, a database backend, and ideally a quote workflow — all built, hosted and secured.
- Ongoing maintenance. New vehicles, corrected figures, bug fixes, and hosting all need attention indefinitely.
None of these are one-off jobs. The data especially is a living thing — a database that was accurate two years ago looks dated today.
The cost of building
A custom build means developer time (typically thousands of pounds up front), the effort of sourcing or compiling the vehicle and gains data, and a permanent maintenance commitment. For a manufacturer of tuning software with a dedicated team, that can make sense. For a tuning business whose real job is mapping cars and booking work, it is usually a distraction that never quite gets finished.
The cost of buying
A ready-made vehicle gains lookup flips the maths. The vehicle database, the gains figures, the software and the hosting are all maintained for you, and you embed the finished tool on your existing site with one snippet. Pricing is typically around £17/month with no setup fee — less than a single remap job, and you are live in 24 hours rather than months.
Crucially, "buying" does not mean losing control. A good tool keeps the database editable, so you can override any figure to match your own maps. You get the speed and low cost of a ready-made product with the accuracy of your own data.
A quick comparison
Build your own if…
- You are a tuning-software company that sells data as a core product.
- You have in-house developers and a budget for ongoing maintenance.
- You need bespoke logic no off-the-shelf tool offers.
Buy a ready-made lookup if…
- Your core business is remapping cars, not building software.
- You want to be live in days, not months.
- You would rather edit figures than compile a database from zero.
- You want predictable low cost with no maintenance headache.
The bottom line
For the large majority of tuning businesses, buying wins. The hard part of a remap database is not the form on the page — it is the data behind it and the upkeep that never ends. A ready-made, editable lookup gives you the result without the burden, and lets you spend your time where it pays: mapping cars and converting leads.
