everything is electrically perfect it has omex 600 its not the head gasket because its only rebuilt a few weeks. i only got it mapped to .3 bar , 145 hp + 163lbft last week(clutch kept slippng on day of map, should be around 200 hp) but it only has water in the rad no coolant yet.. the fans are mounted at the very front of i.c the rad sits in behind maybe that is it??? when im on the motorway the gauge goes back down to middle level but when im driving through the town it stays at the "N".. would that little degree be enough to over do the head gasket??
