Those JKM boys know their stuff , went to have car remapped first time and they advised my divertor valve was dud so back to VW to replace . VW obviously were not sure but I insisted it was valve and they checked and agreed. Back to JKM for map and all was good. Then 2 weeks back car was jerking about so mailed JKM , they said either plugs or coil pack. So back to JKM to have map taken off and back to VW to advise its jerking and its Coil packs or spark plugs. They advise coil packs were changed 3 months back but……….ah yes , I still have original spark plugs from 2005 on !!!!! So new platinium plugs fitted and back to JKM to have map re installed. Car is amazing now, the divertor valve and plugs have made a massive difference.
Thumbs up to JKM .
