We understand that some of this information may be difficult to obtain and detail, however the more you can provide the easier it is for us to get you booked in. We may also be able to advise some small changes to your specification which could help get the best from your vehicle.

We are always happy to speak to you and give you more information on the above, so if you're unsure please feel free to email or give us a call with any questions.

To secure your booking in the diary we require a £65 non refundable deposit, which can be paid on a card over the phone, via Paypal or through bank transfer. The deposit will be deducted from your final bill.


What to expect on the day of your booking...

Upon arrangement vehicles can be dropped off at our workshop based in Coventry up to 24 hours prior to your booking, or on the morning of the booking date.

On the day of your booking the vehicle will undergo a few initial checks to verify that it can safely undergo the tuning process. These may include:

  • Brief visual inspection
  • Engine compression test
  • Spark plug check
  • Smoke test for air and boost leaks
  • Fuel pressure test

Sometimes during these initial tests faults are discovered with the vehicle that could potentially prevent your vehicle from being tuned. If there is time allowing we may be able to repair these faults at an arranged additional charge.

After the vehicle has passed the initial tests, it is mounted on the rolling road and the ECU is fully custom callibrated. We take this tuning very seriously, and to get the best outcome from your vehicles modifications this process can take a number of hours. Depending on the modifications it could potentially take most of the day. 

Depending on your vehicle type and modifications, it is sometimes possible to carry out the tuning work to completion on the day of your booking. However we would usually expect the vehicle to be left for a couple of days, especially if faults need to be rectified, or we are fitting performance parts to the vehicle prior to tuning.
