525td to 525tds

[uk525td]

Hi guys thought id try and start a thread about hte differences between the 525td and 525 tds.. why??? well i bought an ebay chip for my td some time ago, claimed +20 bhp, and it feels it, of course the tds already comes in a lot more poweerful than that, and there was a chip available for that motor at the time, taking it to nigh on 170bhp if i recall...
Now, i had hte thought if i could find hte differences between the td and tds i may be able to put a chip in for a tds....

So far all i ever managed to find out was that the tds has an intercooler......
has any one got any further information, or a tds that they fancy taking a few photos of hte engine bay?

Oops, i meant to say im talking about the m51 engine, and if it matters, in the e34 chassis.

and to add to that, i jsut found a fernch forum and attempted ot translate it, they mentioned something about a change in diesel pump.... maybe this is a no no now.....
