Just got my 2004 E55 Yesterday - What Quick/Easy/Cheap HP Mods Should I do first?
What else would you recommend, perhaps a Jet Chip rather than a full tune to get small, incremenal HP gains? Was looking for mods under $500 if those even exist on a MB.

Thanks!

Don't feel any peer pressure to immediately start modding it though..Maybe give it time to get used to the power you already have? That will also give you time to save for some big boy mods!
you can get some euro impact strips and window for 500 or X-pipe for noise.
maybe a used pulley - but no tune
The worst thing I see now is that new E55 owners not researching about IC pump, IAT's, H/E and data logging.
1) buy the Johnson CM30 pump about $150. This will atleast give you piece of mind your pump is not bad or buy a stock one too. Search about bleeding your IC system.. very simple and cheap.
2) Split your IC system. There is a sticky about this. Very simple and cheap to do. Any mechanic will can do this in about 1 hour with a cool car. Again bleed your system. Basically its removing 1 stock 3/4 "T" connection for 2 3/4" splices and adding a small reservoir.
3) Remove the plastic cover under neath your wipers. its blocking hot air from leaving your engine. Unless you live in a area where it rains heavily, you dont need it.
4)buy a data logger to monitor your IAT's. Please don't race anybody until you sure you have a healthy E55. Data logger connects to a lap top or could be a plug in device like CarChip
All these things are on this forum for you to research.
enjoy your car.. there is lots to learn about it.

Being that you bought it used, as did I, I would allocate the first $$$ to maintenance. Flush the trans fluid, flush the brake fluid, o/l/f, and whatever else needs attention.
once you look at the pictures you will see how easy it is.
The reservoir hits higher and there is a line that connects to the IC system via a T.
Search bleeding.. Basically there is a nipple that is plugged. you will need hose and route to your reservoir. Run the car and let the coolant flow to the reservoir. The Reservoir will feed coolant to the system.
When I started building my track car the Miata community was full of answer but no one had any reasons as to why and after a while I was getting tired of being steered down the golden path. I am hoping to not do this with my new E55
As I live in Phoenix I figure I should get this done now as it gets to 115 in the summer and I drive 100 miles a day to and from work, everyday, in traffic.
Thanks again.

As far as the trunk reservoir goes, if you do the install yourself you could definitely get away with less then $500. With the rear reservoir the only advantage I see with it is at the track when filled with ice.
Then I drove the car to get tints, I recommend 35% in cabin and 20% on the trunk window. It looks clean and the police dont seem to mind it!
After resonator delete for a bit more sound, well, not much more but I think your brain is fooled to think so because you watched them rip apart the exhaust! Still go do it.
Rims powdercoated, and car detailed. The BEST money I've spent thus far (its been about two months since I got the car) is on a LET tune. I got a great deal from Jerry (~$500) and I was blown away with the results. I was not so much blown away and racing Ferraris, but for the money I spent its jaw dropping improvement in speed and performance increase. Hit me up, I'll forward you his #. And good luck!
for me the first thing i did to my car was full fluids flush from front to rear and then full brake replacement from front to rear and added stainless steel brake lines and motul blue fluid.
from there look at tunes intakes pullies and dr's for the track. any i/c cooling mods will keep the ponies racing for longer times and are a great improvement
Searching on it now.
Thanks again.
