Ok, my DPF has now been removed, my EGR has been disabled and the engine remapped.
I also got a Longlife custom twin stainless exhaust made up at the same time.
I've now had the car back a day, done about 150 miles so far and I am VERY VERY impressed! Steve at Motormech really knows his stuff and we chatted for a good while when I picked the car up. He said the car now drove very well.
He wasn't kidding. The car drives completely differently. There are no flat spots at low rpm - there power is always there. From as low as 1300 rpm there is a very reassuring surge everytime you press the throttle. Once the car gets to about 1500rpm you're really getting huge torque and the car just flies. Its just so easy to drive and so few gearchanges are needed.
I would compare it with driving a much larger engined car - it just effortlessly pulls everytime you put your foot down. I've also been getting much better fuel economy (even though I've been giving it a good "test"). I got an indicated 40.5mpg before the work and its now showing 43! Not bad.
Of course I also get a little more noise than before as I had the exhaust done as well. Hardly any difference from standard to be honest but I get a nice deep burble sound when it gets on boost.
I asked to keep the old DPF unit. The thing is HUGE. They had to butcher the unit a little with an angle grinder to remove a sensor that apparently acts like an air flow meter. Not sure quite what it is but you can certainly see that somehting has been chopped out.
One thing I didn't realise is that the DPF unit is in fact a DPF and catalyst combined. There is a gap of about 3" between the two, but they are together in the same casing. Luckily, diesels are only tested for the opacity of the smoke produced (not HC or CO etc) so it will still pass an MOT fine without a catalyst and it gives you a very free flowing exhaust.
I'll take some pics of the removed DPF in a few minutes and post them up.
I'm massively impressed with everything about the conversion. I've spent much of my driving time today with a massive silly smile on my face every time the boost kicks in! It is just SUCH a difference to standard.
For £360 (£300+vat) I think its a bit of a bargain. Of course I also had the custom exhaust done and a small service at the same time. My total bill was just over £700.
