leon mk3 cupra 280 boost

    Cupra 280 low boost

    My 2015 280 has a problem. Bought new in 2015 and now has 55k up. Full service history at seat. Always warmed up properly. I have noticed the performance dropping off. It now is very sluggish from 3k and then does build some boost up to red line. Feels like a 2 litre 16 valver with no turbo...
