Howdy ol'tony,
Well it's only when I have tried to "over take" that I have noticed it -so I haven't had the chance to see any smoke! I drive like an ol'mole 90% of the time so I don't notice it- I have a great spot to test it now so I will give you some more info tomorrow.
Glows got done with injectors and timing chain 10'000k's ago.
I have done the egr mod(both).
Exhaust is 3'' .
Wastegate maybe flying open @ that rev range! I will keep an eye on the gauge tomorrow.
Turbo is maybe 1000k's old (Forefront eng.)
Filters done, air filter done.
(CAS or CAMS alignment) What are these you speak of stranger , an instrument or component ! tell me more..
I was thinking fuel feed too , but it happens to sudden! you can back off slowly and does nothing but coast at say"half throttle but let off completely and back on the gas and away she goes.. This ute I tell you, it just goes on and on!
