Chaps, i know we are not boy racers but im interested to know what speeds you get out of your 1.9TD Xantias.
1, Comfortable cruising speed on the motorway (I get 65/70 mph before it starts to sound like its being pushing)
2, Max speed before red line (i hit 95mph once and it was being floored)
I know mine is way off what it should be for reasons yet unknown and my rev counter doesnt work but i wanted to see just how far off it is
What have you had out of your TD Xantia?

Vince I'd run through the basics, make sure your air filter's clean, your mixture's right, you're turbo's making full boost & your rev limiter's not been set to low. Also that you have the correct size wheels fitted. For what it is mine shifts, it's standard & on 'my local race track' along the flat (ish) will pull 125+. Disclamer... speedos aren't always that acurate & I've never really measured it on the SavNav but either way you should get alot more than 95 out of it.

Using my tom tom in Cassy before I swapped her gearbox, I got 110mph on diesel, ran out on the motorway and added veg and got 115mph
Now though 110mph seems a push, but that's with the 90Hdi gearbox fitted.

Our 95MY 1.9TD estate has always cruised comfortably at an indicated 3,000rpm 80mph (about 77 true). We regularly visit family in South Devon (from Gloucestershire) - traffic permitting, I don't expect to come out of 5th gear between M5 J14 and the Ivybridge turning off the A38. We expect to do the 133 miles in under 2¼hrs including a quick 'comfort' stop at Taunton Deane.
I've no idea what its maximum is, but on gentle motorway downslopes the speed will creep up to an indicated 90+ if I'm not paying enough attention to speed. It will comfortably rev to 4,000 rpm in 4th to overtake which equates to a true 102-ish in 5th.
Turning to a lack of power. Our Xantia was gutlessness for the first couple of years. Not having driven another one to be able to compare, I put it down to modest power output in a largish, heavy-ish estate. Quiet, comfortable, economical, doesn't smoke at all, doesn't use oil, just didn't go - until I recently made a determined effort to find and fix the slight oil blow somewhere above the cam box.
Eventually I found a split hidden on the underside of the air pressure sense pipe to the injector pump (the small black 'rubber' pipe from the large diameter plastic air pipe to the top of the Bosch pump) directing a small blast of oily air at the top of the cam-box. The small diameter of the sense pipe meant air loss to the inlet manifold would have been minimal, but the much lower pressure sensed by the pump was causing serious under-fuelling at full turbo boost. Replacing the pipe has transformed the performance. With 20/20 hindsight, really obvious!
Yours really shouldn't sound strained at 65/70 (true or indicated) - it should be just getting into its stride - unless it's had a replacement transmission taken from a petrol model (lower final drive ratio). Unfortunately the BoL gives absolutely no data on ratios or how to identify transmissions.
The simplest causes of poor performance from any diesel are a shortage of either air or fuel going into the engine.
The first question is "Is it a Smokey Joe?", if not you're looking for fuel starvation:
Check and clean/replace all the filters, including the tank filter.
Boost pressure sense failure - as above on mechanical Bosch systems (no ECU on OSF inner wing), or poor boost sensor connections on a later engine.
The 1.9TD fuel system (Bosch pump) has no separate fuel lift pump - the fuel system depends on adequate 'suck' from the injection pump - any slight leak lets in air, causing fuel starvation. Various threads on this subject.
Check for a (partially) collapsed fuel pipe - particularly between pump and filter (again see threads).
If it smokes, the simplest cause is a filthy air filter.
Best of luck
