What do you guys think? Has anyone used this company?

I just can't imagine why this modification would not be detectable by your BMW technician. If it changes hp and torque, the tech would be able to notice it as well.....wouldn't you think?? <_<

I don't know anything about this firm, but I like the projected results: +23HP +58 ft-lbs torque! Does the top-end speed limiter go away too?

I would certainly think about doing it - and the price is not too bad at about $750. The only hitch is shipping the ECU unit to them ... which could mean you would be without a car for at least a week, I would guess.

I thought about getting this done to my 550 too (as soon as it gets here). I was hoping that Dinan would come out with their own, does anybody know if they will anytime soon? I would just feel weird about shipping a piece of my car away for who knows how long.

ok, here it goes

On normal dealer level using the dealer equipment, a good remap will not be detected, especially not on a normally aspirated engine.
They could find other air mass values etc. on a turbo'd engine (like the td's), but still could only suspect the remap. To read out the ECU to clearly detect a remap, the dealer needs to take it out and send it of to BMW HQ. A good tuner alters your map without triggering the flash counter, too, so the ECU wouldn't show it had a re-flash done.

Worries about warranty are debatable, too. Every dealer licks his fingers for warranty work, as they can charge the full whack for parts and labour back to HQ. Before HQ gets the warranty bill, your car is already done. To get the work from a private customer they might have to make sacrifices to win the business.

I will have my 535d done by a buddy of mine from www.e-maps.co.uk , but although he does travel, a ticket to the US would kill the deal, I'd say.

iirc, DMS automotive have a US subsidiary and an excellent reputation. You could contact Mike Cooper through www.dmsautomotive.com and I am sure he can assist you, f.o.c. and put you in the right direction.

He should be able to further dampen your concerns about the issue itself,
