Southampton · Stage 1 Remap
What is Stage 1 remap in Southampton?
Stage 1 is the standard upgrade for a turbocharged car or van — a custom-written remap on the standard hardware, typically adding 20–35% more power and torque with no mechanical changes. It’s the highest-value, lowest-risk performance upgrade you can make to a modern turbo engine, and Boostcore provides mobile Stage 1 remaps across Southampton and the SO postcodes.
Common vehicles we remap in Southampton
The Stage 1 candidates we see most often in Southampton are the VW Golf GTI / GTD / R (EA888 Gen 3 2.0 TSI / 2.0 TDI), the BMW 320d / 330d / M135i (N47 / B47 / B48 / N55), the Audi A3 / S3 / A4 (2.0 TFSI / 2.0 TDI), the Cupra / Leon (2.0 TSI), the Ford Focus ST / Transit Custom (2.0 EcoBlue / 2.3 EcoBoost), and the Honda Civic Type R. Every one of these responds well to a custom Stage 1 tune.

Frequently asked questions
What are typical Stage 1 power gains?
For a turbocharged petrol, 20–35% more power and torque. For a turbo-diesel, 25–40%. Specific examples: Golf GTI Mk7 +80 bhp, BMW 320d +50 bhp, Audi A5 3.0 TDI +60 bhp, Transit Custom 2.0 TDCi +40 bhp. We publish realistic figures, not optimistic ones.
Is Stage 1 detectable by a dealer?
A well-written Stage 1 tune on a healthy engine is generally undetectable by dealer service tools — the standard diagnostic reads will still look like factory. That’s not the same as saying it’s invisible to a knowledgeable technician, but for practical purposes the answer is yes.
How long does a Stage 1 remap take?
Typically 1.5 to 2 hours door-to-door, including pre-flash diagnostics, the remap, and a post-flash verification scan. We’ll confirm a window when you book.
