DelVal550i

I have owned my 550i Sport Pkg / 6 Speed for about 6 months now and do enjoy the car but have found the drive train performance of this car to be lacking. My gripe is two fold. First the car's final drive is far to low. This is done by BMW to increase the MPG stats for the showroom sticker. The result is a sleepy car under 5k rpm. Secondly, the fact that my 550i Sport Pkg was not engineered with a OEM ECU "sport" button programing map is absolutely unacceptable. Climb into a 2010 5 or 7 and you have 4 adjustments to this effect. My E60 550i Sport Pkg has none. Throttle response is boring and sleepy at best. So, a very heavy flywheel, the wrong final drive ratio and absolutely no throttle response adjust-ability makes this car FAIL FAIL FAIL in my honest opinion. It's the nicest looking sedan on the road but the truth is, it's a boring pig to drive. Heavy, Slow & Uninspiring.

So I am at a cross roads with my 08 550i. Perhaps it's time to sell and get a M3 Sedan.

Very disappointing. Looks porn star sexy but kisses like a 80 year old librarian.

perhaps you need a sprintbooster or Velosity unit

my thoughts exactly...your gripes are shared with basically all e60 owners not just the 550. the SB helps alot with throttle response

I have already walked down the mod path RPI/M5 Spoiler/15mm Spacers so far. How much more do I have to invest to make this car what I know it could be? I would have to chip it, change the final drive and add an LSD, lighten up the flywheel and do the intake. That's going to be 4k? Maybe 5k? It would be a fun car with the right mods but why cant this car come from the factory done right? Those Germans are well aware....

Who wants to buy a 08 550i Sport 6-speed black on tan with 34,000 miles? LOL.

UGGG!

Did you not test drive it? Maybe you need some driving lessons lol. Not sure why your complainging about not having a sport button on a pre-owned '08 model...These all sound like things you should've realized before you purchased it.

none of those items will help with your issue, the spacers and spoiler aren't going to make your car faster

Point on the mods already done is that I'm already walking down the "mod" path and have to decide if I want to keep going or cut my losses now.

Yeah - I test drove it - and loved it - and bought it - but now - 6 months later - the honeymoon is over.
