w211 e500 Ecu upgrade/chip
Searching through the threads here and can't find a definitive answer on a chip or ECU upgrade for my '04 e500. I have seen Renntech's extremely over priced ecu flash but not willing to spend $6000 or so for a car I paid $17,000 for. I saw that someone on dragtimes.com had a chip which gave 25hp and 30lbs of tq. but I can't seem to find it again. If you guys know of anything under $1000 that I can gain HP and low 0-60 please let me know, thanks.
P.S. I know adding a big spoiler would ad at least 200hp but just don't like the look..... hahahahahaha

It just doesn't appear that chipping/flashing MBs is popular for whatever reason. I've seen several explanations, but I won't repeat them because I can't separate the wheat from the chaff on this one.
25 HP / 30 ft-lbs TQ would certainly be nice, but you've already got the 500. Also, you never really know what else may be affected with the chip/flash. From what I can tell I think you're better off leaving it alone.
The big spoiler might be the best HP/TQ improvement you can make... that, or the neon light shining from the undercarriage.
Best of luck.

chip really boosts performance on a when coupled with forced induction. with your E500 you may want to consider air flow modification (intake, filters and exhaust). This will increase HP and fuel economy.
