Yes but how much power did you actually gain? I'm not saying it's all about power gains - remapping can give other benefits as you say - smoother power delivery, better throttle response etc. but power gains are what we're talking about here.

On what basis do you make the statement that you wont get more than 5bhp from remapping an M54?
I'm quite happy to agree remapping companies are often economical with the truth - but they are with the quoted power on the diesels as well. The 330d until 2003 is 50bhp down on the 330i it's going to take a lot more than a simple remap to make up the performance difference.
Based on the experiences of others, people who have actually dyno'ed their cars before and after remaps and the fact that N/A cars are inherently difficult to get large gains from.[TW]Fox;15321828 said:On what basis do you make the statement that you wont get more than 5bhp from remapping an M54?
I wouldn't be so sure. The 330d is turbocharged and there are therefore quite sizeable power gains to be had.
We could argue over figures all day long, but the fact is that a remapped 330d will be both more powerful and faster than a remapped 330i.
Have you even driven a BMW let alone an x30i or x30d? Your profile says you are an 18 year old student?
In what way is it a 'fact' that a remapped 330d will be more powerful?
According to E-maps even when mapped a 2002 facelift 330d is not even as powerful as a STANDARD 330i let alone a mapped one
If you live in the sort of world where it is 'fact' that a 220bhp car is 'more powerful' than a 231bhp car I can't be bothered with this discussion.
Its fairly obvious you're going to get a bigger percentage gain from a remap of the diesel, but no way is it going to be more powerful.
I'd love a 330d myself, they're almost built for my purpopses, but I'd be under no dillusions that it would be quicker than the 330i.
I think my car's got more torque than an ST220 (and feels relatively quick on boost), but I wouldnt go around saying it's the quicker car...

Well as i stated earlier it helps if you sort the air in and exhaust out. I had a BMC CDA on the in and a 3" straight through exhaust at the time and saw 22BHP.
Overall though the car was just so much nicer to drive, 7800rpm limit was fun as well.
Well as I've said above a remapped 330d will see far more than 220BHP, more like 250BHP+ depending on who you go to. There are plenty of DMS 330d reviews about, go and have a read.[TW]Fox;15321917 said:According to E-maps even when mapped a 2002 facelift 330d is not even as powerful as a STANDARD 330i let alone a mapped one
Why do I always feel like I'm diggin myself into a hole when I express an opinion on this forum?

Because a bhp figure isnt an opinion?
What! You won't get 250bhp out of a 184bhp M57 without it lasting about 40 seconds!
Are you sure you've not confused it with the 231bhp E90 330d?
Of course, but we're talking about just remapping here.
Yes, but how much of a gain do you think you would have seen from JUST a remap?CS||nuTs said:
A Clio 172 is a pretty highly stressed engine as standard - 172bhp from a 2.0.
The 330i has 3 litres yet only 231bhp.
Not reliably they wont.
Just looked it up, E-Maps (Who are very reputable and don't tend to exagerate) claim 248bhp for the 330i, so an increase of 17bhp.
They claim 220bhp for a 184bhp 330d and 245bhp for a 204bhp 330d.
Just for a bit of context regarding how well you know these cars etc - what do you drive Alex?

Why do I feel as if I'm banging my head against a wall here?
Go and do some research, look at the figures, a remapped 330d will be more powerful than a remapped 330i the vast majority of the time.
With both cars at stock, I'd agree. But with both remapped I see no reason why the 330d wouldn't be faster.iaind said:
Of course not, that would be a bit dim. But we're not talking about torque here.iaind said:

Because you are posting rubbish and trying to argue with people who actually own the cars in question?
No it won't! I've just provided figures from the E-maps site to 'prove' this pointless arguement. You can't reliably map E46's to 250bhp+ irrespective of the variant of M57 they have.
You CAN with the E90, but are talking E46.
Have you ever driven a car with either an M54B30 or an M57B30 in it? Just a straight yes or no would be good here. I'm just trying to guage what angle you are coming at this from.
It's not about knowing the cars at all. I've not claimed to know what these cars are like to drive, what the gains mean in reality on the road or anything - we're talking about facts here. If you're really interested I drive a Golf.[TW]Fox;15322035 said:
