hi,Datatek thank you for being so prompt on a reply to my question, my rev`s are running at 850rpm wich as i said are ideal with the creeping in trafic jam`s but not down hill gradent`s such as wet tracks without the engine and gearbox being used as a brake and should help with handling and control and not rely on the foot brake if i loose control on the foot brake and it over runs il have resort to plan B seat belts OFFand hand on door handle and jump and hope for the best
