Have to admit that I had come to accept the sluggishness of my 2.5 DSE. In all other respects it is the best car I've owned but was continually hunting for a few extra BHP and avidly following any postings about others suffering the same problem.

Until today! Thanks to the Landyzone Gurus and their comments about the MAP pipe, I found that mine too was disconnected and may have been so for the 4 years since I've owned the car! Missing BHP found then!

Only difference is that I found the connection nipple under the manifold adjacent to No4 Still, it did the trick and whilst this is never going to be a roadburner the car is much more enjoyable to drive, especially when 'pressing on' a bit.

Thank you one and all!

MAP is one, theres more horses to be found if you look a little closer ;)
Mine was originally sluggish, TomCat always told me they can shift and he was right I promise you. I don’t even have a chip or box either.
 
I drove around for over 2 years with a broken MAP, reverse was really bad, wouldn't even drive up a kerb, roundabouts were a bloody nightmare
 
Intercooler clean-out sounds like a good call. Anything affecting air flow sounds like a logical gain. Reckon it is a bit of a potch though, so It will have to go on my to-do list for better weather.
What's the best stuff to clean it with? I'm thinking Traffic Film Remover or paraffin.

I was told to use acetone and leave it overnight, and give it a good shake
 
The old owner of mine used petrol and a bog brush?!!
By the time he'd finished he was black bright with a clean manifold. There originally was 3mm of crap inside the manifold.. Egr dust and the oil film from rocker cover and turbo weep. It sounded like a fire engine when it started up. Nice and crisp. :D

Acetone, I used petrol. You plugged it up and left overnight (this also shows up leaks), then kept flushing it through with the dirty petrol - it gets blacker and blackerer, when I was happy I did it again with fresh.

Make sure it is entirely dry until refitting!!
You have been warned ;)

Make sure it is entirely dry before refitting!!

Better than easystart !!!!!!!!!!!!!
 
It evaporated that evening and overnight, don’t know if it had ever been cleaned before but it made considerable difference in power and mpg

I use petrol. Just leave it in the sun to dry while having a cup of tea and a quick blow through after and it is fine. Does start easily after!
