Frequently Asked Questions.

What are 'Agents'?

Agents are the name we give to trusted individuals or businesses who offer GKR remaps. These are part of our agent network – authorised & approved to provide the full GKR experience remotely from their own premises.

What is a vehicle health check & why do I need one?

We offer free health check’s on any vehicle we tune in-house here at GKR. The reason being, a healthy car achieves top results! Who doesn’t want that? Of course, this is also for you and your cars protection – tuning on top of underlying issues can amplify outstanding problems or niggles.

Will you tune a vehicle with error codes?

Yes, sometimes vehicles have error codes that may not interfere and cause us any problems. We check fault codes as part of our health check and advise if any substantial problems are found.

Can you convert vacuum operated turbo's to electronic?

Yes, we can convert vacuum operated turbo’s to use a more responsive electronically controlled actuator. We’re also able to fit turbo’s from different models & brands – mapping them to work in situ.

For custom stage 3+ requirements, please contact us directly.

Can you remap the gearbox?

With most auto BMW models we have the ability to apply XHP software, essentially mapping your gearbox to predefined stages, much like our tuning package’s

Please contact us directly to discuss this.

Understand Tuning

Benefits Achieved From A Remap.

With the most obvious benefits being overall performance improvements, the true potential of remapping a vehicle based on the drivers requirements is often forgotten.

Increase Performance

On average we release an additional 15% in BHP from a vehicles stock tune, and around 30% on average increase in torque.

Improve Throttle Response

It's great having those big numbers in your BHP bank, but how does it drive? Do you have immediate pedal response or a lazy booster?

Increase Fuel Efficiency

You may not be specifically looking to increase your MPG, but, vehicles we tune are often much more fuel efficient. Thanks to increased engine efficiency.

Smooth Power Delivery

Having all your components singing in tune from the same sheet is the key here. Smooth & consistently power delivery throughout your RPM range.

Feature Solutions

In the chase for power certain things just need a creative solution, then you need to tell the ECU! ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎

Modification Adaptions

Certain stock components just won't cut it. We get that, they need to be bigger... but, they also need to work like they're from the factory too.
