Hello together N mate of me who is actually well acquainted with cars, this week my 406 Coupé 3.0 V6 drove with 190 Ps BJ 99 and 176 tkm sample. He meant that of the alleged 190 Ps is not much to feel and he has only 150 – 160 Ps after his feeling. That smells huge to me and therefore my question….. How can I activate the possibly lost horses again? Maybe by new spark plugs/cable or new distributor??? What lies on such a loss of performance due to age and what can be done there. Ps: My more well-known gulf GTI was driving before and he thought he would be much better off ….
