Loss power, slow accelerating, turbo

[Mr Hagg]

I have no issues with a man not able to speak english at all just that sometime we may not be able to translate when is needing done or what issues are and so on.... I get it all the time. Most of the time I have to have someone translate and then we can get down to it... But power lose is just that I see to many times these engines go into a silent derate and with codes being blocked you never know root cause.
