Hi Chris, Many thanks for the information. No it wasnt raining when i took took it for ths cambelt change but i did hose all the salt off it when i got there! From what Steve G said the MAP has no power to it, it was the first thing he mentioned when it was remapped two years ago and has been excellent since with the Premier Power ultralight flywheel.. I shall get in touch with Steve and see if he has the TPS settings on my file for the ECU, I shall put a tube over the MAP opening too and also disconnect the battery...just in case!
