If the thin pipe from the turbo to the Injection pump was split, what symptoms would you expect? Off boost black smoke when accelerator pressed hard? Lack of guts at higher boost and speed?

the pipe itself is quite bendy and long (technical term), so replacement just to try it doesn't seem to be a viable option.

Whats your thoughts, or is anyone keen to split their pipe and report back? :)
 
Is that a yes to splitting your pipe? :) Thought not... finally found the part number, and for 20 quid, its worth a try.

it needs replacing or you wont get the extra fuel with the extra air turbo chucks in and so the extra power

That was my thinking - the boost is good, but there's no corresponding power when pushed that bit harder - such as 50mph uphill in 4th/5th - that boost is escaping somewhere!

Why not just try it yourself? Disconnect the pipe at the banjo on the injector pump and go for a drive, would give the same results as a big split
 
Then if you did it, and you had even less power you could be fairly confident it is ok. Could always try disconnecting it at turbo T piece and blowing down pipe, if you get airflow you have a leak, if not then to prove its not blocked disconnect at FIP and trying again. This time you should get airflow. At the end of the day it is a single pipe and not that hard to prove a leak or blockage.

How did I not think of that? What a muppet I am today. I blame alcohol. Thank you :)
 
Turns out, the t-piece clamps were loose just after the boost gauge fittings. Note to self, look for the obvious first! While fiddling, took the time to adjust the injection pump too :)
