Hi, have a try with my C20NE Ere just doesn’t want to get over the 190 on the highway anymore… He can’t say that better because he doesn’t have any wheels, but what can it be about… My lambda probe, by the way, lights up even if I go underboard or give it a little gas.. but then it’s immediately out.. can that be on my camshaft? Was the first 2000 ! km never turned over 3500 rpm.. Engine data: km: 12000 km Age: 1 year Tuning: cams le lexmau intake manifold Lexmaul K&N air filter Downstairs I don’t feel anything but upstairs at 5000 rpm I have the feeling he gets no air anymore! Would be nice if you could give me nen tip! A colleague of mine thinks that with the lamda probe is related to the nock because of the changed exhaust gas coming out! And what else can I do that I can tickle so round abount 150 hp out of the engine! Mfg
