    Default Strange engine behaviour during acceleration at high gear and low revs

    Hi there
    I've got strange behaviour of my engine in my Corsa:
    when i drive at high gear (i.e. 4th) at speed of 60 kmh (about 2k rpm) and i wanna accelerate more vigorously engine or turbo has some kind of lag -- it's like it needs to pump more air and after that strange pause (duration about 0.5s) it accelerates properly.
    This behaviour doesn't appear when i'm accelerating from 1st and so.
    It appears on cold and warm engine
    Do you know what should i check and if its something broke or its just how it works?

    60kmh? Isn't that 25 mph? Or is that 40mph That too slow to be using 4th and boosting/speeding off

    Should never lynch a turbo car, I.e apply high load in a high gear at low rpm. Turbos spool and flow at specific rpm and high load should only really be applied then.

    Totally agree with other 2 , too low revs for 4th to accelerate, it’s bound to get lag, if you dropped it to 3rd or even 2nd and accelerated and it didn’t pick up then you have a problem and I would be worried but I’m sure it would just spool and be on boost
    I take it you’ve not had a turbo car before this?
    You have to drive them differently to get the best out of them
