If you have any queries don't hesitate to get in touch.

If you're enquiry is calibration related (engine mapping or other ECU work) please note that we do not work with factory engine management systems other than those found in Renault Sport models. We don't re-map diesels or other factory petrol engines. Nearly all of our work is with standalone systems found in competition track, drag, fast road and kit cars.

  • All email's are replied to within 24hrs (Monday-Thursday, excluding bank holidays)
  • Orders placed before 2.30pm Monday to Thursday are dealt with and dispatched the same day, all being well.
  • A note from Chris: It is much appreciated if initial contact can be made with email. Between the web shop, work shop work and rolling road work there is very little opportunity for telephone answering. We realise this isn't always ideal and I apologize in advance but you can be sure that we are happy to call you back when requested as soon as we get chance.
