Ive got this weird boost type problem. if i change gear at high ish revs say 5000 then put my foot down hard in the next gear, nothing really happens for a while about 3-4 seconds an then the turbo comes in with force! any ideas?
No fault codes. Charge to pancake to intercooler to throttle body air route, all hoses new, and tight as you like.
I am running standard, want to sort this out before I map it, sometimes I feel it lower down in the rev range too, but at high revs it does it everytime.
Has anyone else experienced this?

You will get some lag obviously.
Faulty N75 :undecided:

I know its not going to be instant boost but this is arount 3-5 seconds of lag! to the extent of I lose a fair bit of speed only to accellerate again when the boost comes in.
Was thinking a control issue, N75 or N249 (not bypassed yet, this weekends' job) but by no means am 100%.
Its as if the DV takes time to operate (Sometimes), if that makes sense?

sticky actuator perhaps?

This is something I have not come across, when you say "actuator" what exactly are you referring to? N249?

Actuator on the turbo itself

this is a fancy one, but the oem one probably looks the similar

Is there any way I can service/overhaul this?

A good diagnostics session should help you pin point the issue.

Start with logging block 115, from 1200rpm to 4500rpm in 4th gear, post the results up or email them to me and I will take a look for you.
