As some will know, there's been some debate on the forum regarding the tuning capabilities of the 30D. I've had my car on three different Dyno Dynamics dynos over the past couple of years, in different states of tune (stock; MPPK; and now a DMS remap), and have seen a broad and even spread of figures for the DMS remap. None of the figures were close enough to indicate a grouping.

I've wanted to get a fourth set of dyno results to corroborate one of the figures and get an idea of what the reliable output numbers are. Having read Jon's review of his positive experience, I booked a dyno session at Evolve in Luton yesterday afternoon. Very nice/genuine guys and it was pretty clear that Evolve doesn't do ego massaging or bash other tuners.

My car with the DMS remap produced 347bhp and 495lbft at the Surrey Rolling Road forum meet last year.

On the Evolve dyno this afternoon it produced 345bhp and 525lbft. Same car, same remap, same (very close, especially power output) results on two diferent dynos. Nice flat torque plateau between ~2,000-3,500rpm which gives a very linerar throttle respoinse and power output - exactly what I asked DMS to achieve with the map.

Jon's figures when his 30D was running a tuning box were very similar on the SRR and Evolve dynos which also helps to corroborate the figures. The Evolve 30D remap, 344bhp and 540lbft, is producing very similar results to the DMS 30D remap. I accept that's a small sample of engines, but testing the outputs on two different dynos does provide some credibility in the numbers.

As always, let the debate begin

You might want to change the file name to remove your name and reg - or you might not

good figures had my old 330d e92 mapped there 7 years ago. how much they charge you for dyno run. taking my mapped 435d up SRR again at weekend.

Good point. I'll add it back later.

[Tengocity]

There's still some discrepancy, especially with the torque figures, and that could be normal variance I'm sure. How did the actual WHP figures compare?

[mikeoz]

Watsey..are you still running the DMS then?
Interesting comparison thanks.

[smithers330d]

Interesting. I have a DMS map too and would like some independent verification of the outputs because I don't believe DMS's dyno as far as I could throw it! It must have been reading very optimistically on the day my car was in...367bhp! It should be running around 340bhp and 520lb/ft according to them. Might book it in with Evolve then. Should come out close to yours Watsey.

Numbers aside, the map is superb. Very smooth throughout the rev range. I've had it on now since August last year with no issues whatsoever.

Interesting how things have changed with 30d tuning. Up until a year or so ago it was rare to hear of a 30d with more than 315hp, there was even a view that was the limit of the turbo. The norm now seems to be around the 340hp mark for a remapped car. 35ds now seem to be pushing closer to 400hp if figures posted are accurate. Have they found a way to get more out of these cars or are they just pushing them harder?

[mikeoz]

Probably a bit of both?

[SteveChester]

Think my MoreBHP remap was 316 so really adding some power to it these days!

Yes, very happy with the DMS map. I went to Evolve for the dyno run and to hear a bit about their business, not for another remap.

Most of us would disregard an outrageous dyno figure, and for me it wasn't about an ego boost.

The things I liked about the DMS service were the ability to discuss specific requirements for a bespoke map, some other coding tweaks, and the three year free map reload if the dealer was to wipe it with a software update (which I've already had to use, and with zero hassle).

Personally I'm still skeptical of any 30d stage 1 remap dyno figures above 330bhp, but at the end of the day the actual acceleration performance figures of the car don't lie and are much more important than any top trump dyno figures. It would be nice to get an accurate 50-75mph time on the flat from a 330d that has a dyno reading above 340bhp from a stage 1 remap

[teaston]

So did you pay for your car to be remapped again just to get an extra 15lbft torque?!

No. Same car, same remap, as per my post.

You're always sceptical. Maybe there's an alternative reality to the one that you've been told to believe.

Oh, near the end you mention ‘the Evolve remap’

I am also a little skeptical about some dyno figures too having seem some unusual figures previously, and the business model encourages overstatement. They could be real, but it’s hard to be sure. A Santa Pod type test with a series of timings is a good way of proving it.

Not really, just a lot of high inflated dyno readings.
It's the performance of the car that matters though and if your happy with that then that's great

Edit: To be fair in the case of your car it's not strictly just a stage1 remap due to having the upgraded intercooler on the Mppk, it's certainly possible that upgrade could help the car produce a few more horses

Exactly, .. personally my money would be on that kind of test proving that the stage 1 remapped 330d's with decent remaps are actually closer to 325bhp than 345bhp

At 345bhp an F30 330d should be capable of 50-75mph on the flat in around 2.7seconds. These cars do it in around 3.6 stock power, 3.2 at around 300bhp and 2.9 at around 320/325bhp.

I live near Bristol and if you come and visit we can do any tests you like to decide once and for all what my mapped 30D can or cannot achieve.

My car did 345 BHP on the Evolve dyno

I've got a better idea, .. in the next few months I'm getting an F30 330d and getting Simon from Emaps to remap it to around 325bhp (what he quotes), I'm around 80 miles up the M5 from Bristol.. so once my cars ready we can hook up and test both our cars sometime
