All perfectly correct > and normal. And I guess thin air / high altitude does not make it any better.... Do you think these to together could cause this severe lack of boost? Gauge goes only up to half of yellow scale when problem persists. And in that one day I mentioned before, I went only to the border of white/yellow range. > > Have you got one of those 'performance' air filters sucking in air from > the hot engine bay?

Even tail pipe is standard :) I guess I need to check hoses once again. As fas I know, engine is not overheating. At least standard temp gauge show normal temperatures, always. > Another possibility is that after 5 years you have some carbon deposits > that will make the car knock more readily. How do I get rid of that? BR:Z
