2.5-3k i get a nice sound of the turbo.I normally get a slight diesel rattle at 1.5-2k which i think is normal its only there for a slit sec.But that could be the remap as the turbo spoils earlier.Oil is fine and it only has 42k on the clock but it does make noise I think it's from the rail or injectors and that is only when revving at 2500 to 3000 ???
Thanks for quick reply. You guys are great
