2003 E55 mods/upgrades?
 

Hey, I was just wondering what current owners of the 2003 e55 have done with their car and what they suggest to do? I dont have alot of money to spend on it since im only 17but i have about $5,000 to do whatever so i wanted to hear what u guys suggest.Any responses would be appreciated

Your 2003 model should have a blower, so a new software flash for your ecu would give you additionally 40hp and 37ft/lbf.With a pulley change also,would you get about the double.
If your 2003 is the old model without blower, you would gain about 30hp and 15ft/lbf only with a new software flash.

optican,
you're going to have to show me where you keep coming up with these numbers. no one has ever dyno'd 40hp fromsoftware by itself...NO ONE!

ghill,
if you've got an '03, it's the w211 kompressor version. get yourself an asp pulley for $799 from k1motorsports. it's the best bang for the buck possible, worth 40-50hp. you don't needa software update and the extra money it will cost is only worth 5-10hp at best.next, spend the rest of your mod money on aquality installed 100 shot of nitrous. you'll probably have enough money left over for a second set of tires (your current ones won't last long with the extra power) and you'll smoke EVERYONE on the street!

ECU turning will give 28 extra hp using 93 octane.
ASP pulley alone will give about 50hp gain.

don't tease us with those 93 octane ratings...it's not fair to those of us that are stuck with 91!!! ;)

RE: 2003 E55 mods/upgrades?
 

91? Thats the Bottom grade around here.. lol just kiddin....

RE: 2003 E55 mods/upgrades?
 

lol...sure...rub it in why don't ya!

Very easy for you to say NO - butthen again it shows that you don'tknow what we can do with a software at all.Our "standard tuning" file for this cargive 32hp only for software flash -after we tweak on this software is it40hp - lot's of those cars are running around the world -- of course, the better petrol you use - the better power. Believe what you want - I can't afford BS anyone, so this is the clean fact. We have a database of numbers on our site, check that out if you want.

sorry, i already checked out your site and couldn't find ANYTHING relevant...and just because it may belisted on your site doesn't make it accurate. i understand fuel octane rating plays a big role and maybe you're talking about a tune to better than 91-93octane (which should have been disclosed if true), but outside of using race fuel here in the u.s., i find it REALLY hard to believe your 40hp claims when no other tuner can do that...not renntech, not kleemann, not evosport, not powerchip...no one.

Sorry, I was to put this link in - http://www.obdtuning.de/cardb/cardb.asp from our German site (only in German). And yes, all our numbersfits for US 93 octane.
You may of course belive and mean what ever you want, I can't do anything about that.What other tuners make for these cars is not a "leadingstandard" for our numbers -we all make different software (well some of us), and therefore different numbers.
