Southampton · Performance Tuning
What is Performance tuning in Southampton?
Southampton has a strong performance-car community — the VW Golf GTI and R owners, the Audi S3 and TFSI crowd, the BMW 330i and 335i drivers, the Cupra and Leon owners, the Type R drivers, the Focus ST and RS contingent. If you’re chasing more power, sharper throttle, and a more engaging drive from a turbocharged petrol engine, a Stage 1 or Stage 2 performance tune is exactly the right move.
Common vehicles we remap in Southampton
Boostcore provides mobile performance tuning in Southampton and the SO postcodes. Stage 1 is the standard upgrade — a custom-written remap on the standard hardware, typically adding 20–35% more power and torque on a turbocharged engine. Stage 2 introduces supporting hardware changes (downpipe, intercooler, intake) and unlocks significantly more — for example, the Golf GTI Mk7 EA888 Gen 3 2.0 TSI is a Stage 1 favourite, with VIEZU-supported Stage 1 maps delivering 80 bhp and 100 Nm over standard.
Book your Performance tuning in Southampton
The work is the same as a workshop: pre-flash diagnostics to confirm the engine is healthy, custom-written map from a VIEZU-supported calibration library, post-flash verification, written terms agreement, and a backed-up original file. Performance gains are realistic and quoted in advance — no inflated numbers, no over-promising.

Frequently asked questions
What are typical Stage 1 power gains?
For a turbocharged petrol engine, 20–35% more power and torque is typical. Specific examples: Golf GTI Mk7 2.0 TSI +80 bhp / +100 Nm, BMW 320d +50 bhp / +80 Nm, Audi A5 3.0 TDI +60 bhp / +100 Nm, Transit Custom 2.0 TDCi +40 bhp / +80 Nm. We publish realistic figures, not optimistic ones.
Is Stage 2 worth it?
Stage 2 is worth it if you’ve already invested in the supporting hardware (downpipe, intercooler, intake) and you’re using the car for spirited road or track use. If the car is stock, Stage 1 is the right starting point — it delivers most of the real-world gain with no hardware change and no warranty or insurance complications from a downpipe.
Will a performance remap affect reliability?
A properly written Stage 1 tune, on a healthy engine, with regular servicing, will not affect reliability. The pre-flash health check exists to verify the engine is in the right condition. We will not tune a vehicle that has underlying mechanical, sensor, or compression issues.
