O.k it's been a long time since I posted on RR, or even visited for that matter!
But now my everyday car has changed and I've been out having some fun with it at Crail Raceway ... this leads me to some further questions ofc!
The car in question is a Citroen Xantia 1.9 Td Desire estate, when this car left the factory it was de-tuned to a woeful 90(ish) Bhp and it was lucky to see 1/4 mile in 28 seconds with a 0-60 time of around 13 seconds. This was totally Unacceptable and had to be changed!!
The car has a best time on the 1/4 mile now of 17.25 seconds with an end speed of 80.8mph, the 0-60 time is now reduced to between 8 and 9 seconds (only manages 120mph or so before it's screaming in the redline though).
Currently I have only spent around £20 on tuning this car, that was simply because I needed a better boost pin from a 300 Tdi Landrover due to it's steeper performance fueling slope.
The things I have done to add the extra power are as follows:
Fitted LandRover 200/300Tdi extreme fuel pin (made a huge difference on it's own from the standard item)
Performed Governor Mod on the pump to allow more fuel at higher RPM's, Downside is that it revs higher than the rev gauge reads now but that's o.k
Shortened the actuator arm on the turbo to it's maximum limit, I believe it's a T2 Garrett unit and is boosting at around 26/28 psi
Removed the A/C rad from in front of the intercooler so I can get better airflow to the intercooler and use the A/C switch to run the fans permanently if required (no more getting over 90 degrees)
Ripped out the useless diesel filter system and the 8 feet of extra pipes that are not required. Now using an inline filter from a BMW 320D
Made adjustments to the pump to allow the most fuel I can while maintaining 1000 ish Rpm idle!
Changed the exhaust so it's straight through with no silencers or diesel cat
I am craving for more power from this engine, against a friends 205 1.9Td conversion I think I'm doing o.k. He runs a 17.11 and I run a 17.25 but my car weighs in at around 1360Kg and the 205 is allot less!
What else can be done to this setup to generate the extra power that I want without going totally spend crazy??
I would like to think that just adding more fuel would be the answer, If I do that then I get too much smoke and it seems slower because I can't push enough air through to burn the extra fuel on the standard charger!
Any thoughts and pointers are appreciated, I don't want to spend mega bucks to achieve the end goal. I would however like to be down in the mid to low 16's with it!
I forgot to mention that it runs on a Bosch Semi electric AS3 pump and I currently run 100% WVO (waste veg oil and 50p p/l for people who don't know what that is).
Thanks for any pointers if people suggest them!

but the report was that you didn't get noteable power until around 5k rpm, that's no good for daily driving
