Hello all

I have a 545 and I'm very close before ordering an upgrade by DMS. My question: does someone have any experience with BMW upgrades (Petrol, without Turbo)?

Thanks a lot and kind regards,?
Thomas

It depends on what you expect from it : my 545 is remapped and I like it, but the gain you can obtain would be only 8-10 HP .

8 - 10 HP plus is not very much indeed. But DMS offers an increase to 367 HP = 34 HP more than the serie. That sounds tempting, right?

Hey, new guy here. So I apologize for stupid questions, but what is DMS?

AlexFW

They have to say 30 HP otherwise nobody would be the remap .

In other terms, you wouldn't be quick as a 550i .


The remap on a naturally aspirated can only remove some restrictions regarding the pollution emissions and increase the rev limiter .

My suggestion is to go with it: I haven't DMS, but I like very much my remap : it adjusted the 1500-2500 and the 5000-6500 rpm range .

Pls ask for the rev limiter, I'm curious!

AlexFW

It should be the most famous english shop that remap your car . Heard many times here on the forum .

Alex, a remap on our cars in combination with air filter and exhaust will deliver an increase in the 8-10% range. I'm still waiting on my Supersprint, but the noticeable difference I'm experiencing is not consistent with only 10hp - you would never notice 10hp...
After driving 3 years stock, I definately feel the difference from the remap and expect slightly more kick after 4000rpm with the Supersprint on.

My tuner asked me if I wanted the rev limiter increased but I kept it stock as I believe you could only safely mod this in combination with new camshafts with a higher rev profile.

For example the one from Racing Dynamics takes the N62 to 7400rpm (in 5th gear >300km/h)

Part no. 540 62 60 100

I know it's a different story with diesel: but I had my 535 d done by DMS and it was a dream! DMS = www.dmsautomotive.com in UK. From my point of view one of the best tuning companies. Rob Young is a wizzard! They will send one of theire engineers over to Switzerland to do my car!

The upgrade goes to 367 HP and 495 NM. I believe that because they proved it on their rolling-road. And they give a 100 % satisfaction warranty.

I've read the DMS test results about M5 (E60) and the new M3 (see BMW Car Magazine) and both gave a very positive feedback (for normal aspirated cars).

I've been told that the performance increase is not the same as in a Diesel. But the kind of power delivery would be very much better than before.

Best wishes,
Thomas

Someone here said Dinan claims 8-10 HP for the 550i .
Yes, 10% with a good exhaust .



Imho with the stock camshafts the engine might get easily 6800 or more . I will try with next remap after catalysts .

Jetblack promised me some diagrams about 6800 rpm limiter by Dinan, but never seen anything .



This would be an interesting mod!
7400 rpm with M5 cluster would be cool!!
I talked by phone with that man and he told me EUR 3600+VAT for the parts only . That's crazy .
I bet in US he doesn't ask $5000 for them!

Which is the real price in US ?
(Vegas, can you ask to Mr. Federico ?)

andy545

Does that price include the exhaust as well ?
You could ask just for the camshafts and tuning. (Don't forget we need 4 camshafts for our engines - stock camshafts cost 600euro/piece !)
