A little is acceptable, a lot is not...

more smoke = more poke

or so that idiot kept trying to tell us.

Thanks cleaned map at same time as cleaning inter cooler new air filter done all obvious checks coming down to maf have ordered a nanocom but will be trying to plug into one before it arrives. it's good on slow take offs but floor it as you would 4wding and can't see anything behind its like a batman smoke screen

Have you checked that the wastegate moves freely ? If it was stuck open ( unlikely) you would be low on boost. Low boost or excess fuel = smoke.

X 2 check the waste gate. Have you run it with the maf disconnected? With it disconnected the ECU defaults to a factory setting, so in theory if the maf is at fault there should be a lot less to nil smoke screen. A dodgy injector is a possibility though I have not seen 1. Oil in injector loom? Again dont think this happens as a result, but 1 never knows

Do you know this for a fact, or is this what you were told when you bought? Did it always do this from when you bought or is this a recent change?

Definitely should not blow as much black smoke like you have described.

... and replace the crankcase breather(depression controll) valve if you know it's old..this one can cause excess of smoke too
