Chip Tuning Zeist

Pricing depends on the vehicle and the chosen stage. Stage 1 starts around €499, Stage 2 ranges from €699 to €1299, and Stage 3+ projects vary depending on hardware. We give a fixed quote after identifying your exact engine variant via plate lookup or email. Customers from Zeist pay no regional surcharge - the website price is the price.

Every tune we produce is validated on our Bapro BPA 4R HP Linked four-roller dyno under controlled conditions. We stay within safe limits for injection pressure, lambda, torque and exhaust gas temperature. The original ECU file is stored prior to the modification where technically feasible and permitted. A revert to factory can be performed on request at cost, provided the backup remains available and usable (see Article 9 of our Terms and Conditions). The original dealer warranty may be preserved in some cases under partner-dealership terms; we advise per case. See Article 8 of our Terms for the consequences for factory warranty.

A standard Stage 1 or Stage 2 chip-tuning takes 3 to 5 hours on average, including diagnostics, before/after dyno runs and the actual flash. Zeist sits roughly 75 km (about 50 minutes drive) from our workshop in Rotterdam-Zuid, so most customers book a morning slot and drive home the same day with the tuned car. Stage 3+ projects with hardware upgrades are scheduled as multi-day work.

We support thousands of variants of BMW, Mercedes-Benz, Audi, Volkswagen, Porsche, Ferrari, Ford, Volvo, Land Rover, SEAT, Skoda, Opel, Peugeot, Renault, Citroën and more. For each engine variant we develop the file in-house rather than reselling off-the-shelf maps. Enter your registration on gsgperformance.com and you will see whether your car is in the database with measured stage 1, stage 2 and stage 3 figures.

Three things: first, the Bapro BPA 4R HP Linked, a four-roller AWD-coupled dyno that no other independent tuner in our region runs in-house. Quattro, xDrive, 4Matic and S-AWC vehicles get tuned under full traction load, not single-axle approximation. Second, we write files ourselves per ECU revision and fuel grade rather than reselling generic maps. Third, the original ECU file is stored where technically feasible and permitted; a revert or switch can be performed on request under the conditions in Article 9 of our Terms and Conditions.

Yes. Zeist sits roughly 75 km (about 50 minutes drive) from our workshop in Rotterdam-Zuid. For customers who cannot or do not want to drive themselves we offer a pickup and return service on request. Contact us at info@gsgperformance.com or via WhatsApp and we will schedule it. Many customers from Zeist also choose to bring the car themselves and enjoy lunch or a city visit in Rotterdam in the meantime.
