On Dinans website under new products it lists performance software for the 545 and 550, but under the 550 link it does not. Is this avalable or not?

If its available I will go ASAP

 

Just talked to Eric Dinan, he said it will be available in about two months, with similar gains..

 

I'll be the first!! LINK

 

It says "the sofware provides an increase of 8 hp and 6 lb-ft torque @ 6500 rpm". As if you would notice! Or am I missing something here?

 

...in addition, you'll need free flow air filter like K&N, etc. For sure, 8hp and 6lb-ft of torque is never noticiable for a 2 ton car. However, it might help on throttle response.

 

I saw the same thing this morning and did a double-take. I can wait 2 months.

I do think we would notice the impact from the Dinan stuff (CAI, throttle body, exhaust, software tuning), if not so much in terms of torque and HP gains but in responsiveness and a better sound.

But for you MT & SMG owners, the 3.45 differential is probably the best bang-for-the-buck, kick-in-the-pants investment.

 

I'd go for Dinan's suspension package and differential (if offered for slushbox )

 

The main benefits of the software are improved throttle response, raised rev limiter, and removal of top speed limiter. The hp increase is minimal but the overall driving experience is much improved. I just got the Stage 3 software on Monday and it improved the car's driveability....feels quicker on the throttle and gives the sensation that you have a much lighter, more responsive engine.

 

I saw the same thing and was also curious about that but I looked at it again and realized that where it says "Now Available for the (E60) 545 and 550" it's meant to be the heading and then everything below it is a listing of what's available for the 545 and 550. Right beneath, it says "Performance Engine Software-545i" so at a glance could be misleading. It certainly misled me at first..

 

Quick one,

Does BMW still approve Mods done by DINAN? What I mean here is that would my factory warranty still be valid after the mods?? I heard somewhere that DINAN is the only provider that has been certified by BMW. true?
