Hi all,

Friend of mine is interested in the cargraphic race after hearing mine in person. However he does not wish to tune his car. Will the cargraphic race cause a cell light without a tune? I only ask because I have been given mix information. From cargraphic germany they state that the exhaust will need a tune however at rensport they mention a tune is not needed as o2 simulaters are built in. If anyone has an answer to this it is highly appreciated. By the way the car is gulf spec if that makes any difference.

Thanks
