Why not just buy a faster car to begin with, instead of worrying what might or might not happen as a result of tuning?

Can you find us a five seater car that will do 0-60 in less than 5 secs, and with a top speed greater than 170mph, and can better 40mpg on long runs. Oh and costs no more than say, £35K new?

Fair point. Are you still going to return such good economy with those performace figures? The way to increase power on a diesel is to increase fuel supply.

Yup, i had a remapped LCI 535d (ie, the latest one with the 335d engine) and i could get 42mpg on long cruise type runs. In fact, did a tour up through scotland from stranraer with four adults in the car and a boot full of luggage, into glasgow for the day, then up through the highlands, then back into glasgow later in the week - averaged 39.9mpg overall.

Interestingly, a lot of HGV lorries have tuning boxes / remaps done - not just for the power but mostly for the increase in economy.

Just out of interest, how do you improve the economy on a diesel? Just run a bit leaner?

If it were a straight diesel then yes, i'd say turn the pump down. I wouldnt want to start monkeying around with the latest turbo diesels though.

For best economy i use cruise control a lot, and stay out of towns where possible. ie, its long runs at a reasonable speed where a diesel will excel.

Ive always found using cruise uses more fuel

Also, just for clarification, mine was remapped up to 340BHP, not downwards for economy.

Turn the pump down and you loose power.

as above chipped uk is a pecker lots of info on the net about him ripping him off and he even owen me money still !

I did a successful chargeback against chippeduk for a non-delivered product (this was for an epromm chip which he never bothered sending despite several promises by phone and email and a face to face discussion with me at the Autosport show).

A useless company of the 1st order.

well considering someone brought this up from 4 months ago, its best i update it!

Been mapped since

R/R 344bhp and 530 odd ib ft

Datron timed 0-60 5.4 and 0-100 12.5 and a standing quarter of 13.77@104 on the same run, have gone quicker before with a 13.5@105 standing quarter

not doubting any of those figures since its not that hard to get more power out of turbo'd engines...however not sure what the gearbox would say after a few aggressive starts, 1st 2nd gearchanges with 740Nm to handle...

Even if it gave 500bhp it would still be a smelly uninteresting oil burner!

Still piss all over an E39 M5 as well.

What you mean is that it would probably pull away slightly in a straight drag race yes?

Give it some corners, or a personality test and it'd be a different story.

Comparing it to a car that was released 9 years ago is hardly fair though.

It might p*** black soot all over an M39 M5 in a vain attempt not to let a faster car past

Perhaps its just a handful of 335d owners who have a chip on their shoulder and seem to need to justify their purchase by what it is almost as fast as - in Petrol terms

No, what i mean is a 335d with 368bhp will obliterate an E39 M5. Correct, the age comparison is unfair, an M5 does not handle anywhere near as good as a 335d with sport suspension, and the steering is so so at best.

No soot, you've not heard of particulate filters i take it.

I don't have a chip, or a mapped car, i also had an M5 and sold it,leaving the rose tinted specs in the glovebox;)

You cannot beat a petrol car for soul, and you won't beat a mapped 335d with an M5.And round a track, the same driver would be quicker in the 3.

When you've experienced all versions, maybe you'll understand what your talking about a little better.

Do you have a different e92 to the one on my drive because the chassis on that isn't as good as you are making it out to be? Also the auto box would be rubbish on track, it is tollerable on the road just and even then it annoys me. And the steering is artificial too, feels really weird, not as good as the older cars. What would I rather drive on track out of e39 M5 and e92 335d - M5 every time.

I have an E90 with the runflats binned. It was recently at Donington having the daylights thrashed off it, a tank and a half of juice worth.

You can place it within a millimetre, and the steering tells you everything, the box and paddles were very impressive.

I can only assume you have a 320 with active steering as you do not state the model you have. What i am certain of, is you have not driven an M5 with recurculating ball steering. Or you have no idea how to interpret signals from a chassis.

Oh, i don't 'make out' just speak from actual experience.
