Normal for diesel  :wink: You have to shift more as the power band is completely different to a petrol  :smiley:

^^^

At that speed you're barely ticking over and you're loading the engine up.  Also its the quickest way to ruining your clutch.

Power band on a derv is from around 1600rpm to 2500rpm depending on the engine model.  The 150 makes its power towards 3000rpm

On mine I can do 30mph in 5th gear but that's barely pulling 1100rpm  :laugh: :laugh:

2nd at 30mph is over 2000rpm iirc

What rpm are you doing in 4th gear @ 35mph?

far too low lol; turbo has just about begun to spool

Like I said your useful power band is from approx 1600rpm to 2500rpm; drop a gear and see if the car picks up better :afro:

It will be more responsive but again it will mainly fatten that power band and also hold the power a little bit longer  :smiley:
