525 TDS chip - worthwhile?

[Nickhlx]

Assuming I get to solve the starting problem, does the 525TDS (M51) engine benefit from a chip, and if so what does it give and does it make the engine prone to some damage ? I wouldn't be revving it any higher, just hopefully be able to use more midrange torque and better economy when not.
It does seem to be overfuelled at WOT and above about 3500 revs from the visible haze out of the back.
Thanks,
Nick

TDS? Turbo diesel?

Yes - Why, don't you get those ?

The 525 TD puts out about 115 bhp and the TDS about 140 bhp in stock form, here in the UK

apparently yes the deisels really respond to a chip,even the later ones

I've been in a few chipped turbo-diesel audi's and bmw's and it really gives them a good kick up the arse. loads more torque too. i say go for it.

It sure does, but this car is 10 years and 130,000 miles old and I don't know how much reserve the M51 engine/transmission has in it to handle more power and torque - its already the UK TDS spec (140 odd bhp) and there are chips to take it up to 175 bhp, but will it kill it quickly ?

Hi Paul,
I know, generally, but what I don't know is if this particular engine is already on its limit and to chip it would likely mean an early death....

My 2001 E39 530D was stock 193 bhp and I chipped it for 3 years until sold and it was at 230 bhp and 370 ft lbs torque, and with improved mpg.
