If you’re looking into tuning your BMW or VAG car, you’ll quickly come across “Stage 1” and “Stage 2”. Here’s what each one means, what it typically gains you, what it costs and how to choose.
Quick answer: a Stage 1 remap is a custom software tune for a standard car, with no parts needed. A Stage 2 remap is a stronger tune for a car that already has a less restrictive exhaust, typically a sports cat downpipe, usually with an uprated intercooler. A typical Stage 1 adds about a fifth more power on a petrol and about a quarter on a diesel, and Stage 2 usually adds a further 10–20bhp. Stage 1 starts at £449 and Stage 2 is usually £150 more.
What is a Stage 1 remap?
A Stage 1 remap is a custom ECU calibration that works with your car exactly as it left the factory, with no hardware changes. We adjust fuelling, boost and timing to safely release the performance your engine already has in reserve. It’s the most popular option: strong gains in power and torque, sharper throttle response and, on many diesels, better drivability. Every Stage 1 we do is written for your car on our in-house 4WD dyno, after a health check, with before and after runs.
What is a Stage 2 remap?
Stage 2 builds on Stage 1 but is calibrated around a less restrictive exhaust, which has to be fitted first: typically a sports cat downpipe or a turbo-back system, usually with an uprated intercooler. An intercooler or induction kit on its own isn’t enough. Because the engine can breathe more freely, there’s more to be had safely, so Stage 2 suits drivers who want more than Stage 1 delivers and are happy to fit the parts first.
Removing a DPF or catalytic converter is for off-road and track use only. On a diesel, Stage 2 usually means removing the DPF, so for a diesel you drive on the road, Stage 1 is the right choice. Check with us before you buy parts and we’ll tell you what applies to your car.

| Parts needed | None | A sports cat downpipe or turbo-back exhaust, usually with an uprated intercooler |
| Typical gain | About a fifth more power on a petrol, about a quarter on a diesel; torque up 20–30% | A further 10–20bhp over Stage 1 |
| Price | From £449 | Usually £150 more than Stage 1 |
| Best for | Daily drivers, and the choice most of our customers make | Cars that already have the right exhaust fitted |
Which should you choose?
- Choose Stage 1 if you want a big, safe improvement with no hardware changes. It’s ideal for daily drivers.
- Choose Stage 2 if you’ve fitted (or plan to fit) the right exhaust and want the most from your setup.
On most BMW and VAG automatics, tune the gearbox too: it raises the factory torque limits so the extra torque isn’t held back. See our BMW gearbox remap and DSG remap pages. Booking the engine and gearbox together saves £125.
