Hi all I need to get the sky running right up to 4k its running great but at 4 to 5 k the revs go up and down like two times then its running ok over 5k when you rev it up to say 6k it judder in-between 4 and 5 and do a big bang and you get lots of black smoke like the fuel isn’t being ignited right may it be a coil going don’t want to spend lots on it to get it righ pic what comes out this is at 4 to 5 rpm so you can see and see if you now what it may be

Check your turbo pipework and hoseclamps (turbo to FMIC to plenum), sounds like you have a leak thats opening up under pressure.
