Buying a 2011 E350 Coupe in a couple days
What are some tips to make the car faster?
What spoiler and where to buy?
Thinking of getting Sprinter ...thoughts?
Thanks
If you say you want to increase horsepower in your 328 people say buy a 335. If you say you want to increase horsepower in your 335 they say buy an M3. Such an ignorant answer.
Does anybody have anything worthwhile to contribute regarding the E350 coupe? Any common issues? Anything that makes this a good choice in the MB world? What are some of the common mods?
In regards to how it drives, some reasonable suggestions have been noted and will likely be executed such as sprintbooster to get rid of the lag and and ECU remap to at least get to 300hp. Don't need 400hp with the headache of the gas consumption that the E550 provides.
Thanks in advance.
I own a 2011 E-350 Coupe. Owned it for a year and bought it with 17,000 miles on the odo. Absolutely love the car. No problems at all. It certainly doesn't have the E550's power, but it is very responsive. Mine came with a spoiler, so I cannot help with your selection. Do a search here and you should come up with some ideas.
There are several things you can do to make it faster. An engine control module tune, which I did not do. Headers and a tuned exhaust system (expensive), and a SprintBooster, which I installed. Did not add more power, but really livened up the throttle response. The car just goes quickly.
Good luck with your purchase. To avoid additional smart-a$$ responses, feel free to PM me with any questions. I'll try to help.

That being said, if you are set on the 350, I *think* the sprinter is meant just for throttle response right? Not actually making the car faster in terms of power, but in terms of throttle response. I could be completely wrong on that though.
On cosmetic mods, man there are plenty for the body style you are choosing. I'd hit up a board sponsor here if you want anything. Or you can do eBay for some things. I always thought the Lorinser spoiler was nice. Bigger, but not all crazy. rear diffuser, exhaust tips, front diffuser, etc. You have a lot of options.

This purchase is for my wife however I drive a 328i and it is a pet peeve when discussing power upgrade options for my vehicle that everyone says to buy a different car ie. 335 or M3, which isn't exactly helpful advice. Because this is something that already gets under my skin I was quick to respond accordingly. I hope you understand my frustration in regards to the response and why I may have been a bit harsh with mine.
With that being said, NCBob, thanks for the feedback on the sprintbooster, I will definitely purchase one. That is the biggest issue with the car, not that it doesn't have power, but it doesn't respond the way we'd like. I think from what I've read in the last few days this is a must for us.
Hillcreative you are correct, but it's the feel not the dyno that will be important so the sprintbooster sounds perfect. I think it's worth looking into the ECU mod down the road as the extra 35hp would be great.
Snakedoctor thanks for the tips!
Fourcircle, unfortunately my wife has fallen in love with the colour combination so we have purchased the 2011. It's grey on grey and we were having no luck finding any other e coupes with grey interior. This is the same combo she has in her G35 coupe and that's the reason we want quicker response since her current car goes right away. We understand it won't drive like a G because it's a much nicer, luxurious car, but overall, still drives like a beast. I would buy the E550 if it was me, but my wife doesn't want the extra gas bill as she drives a lot. Plus that kind of power will only get her tickets lol
Something in between would be perfect, but I think these two mods will do the trick. I will check for a sponsor that sells spoilers and we're good for a while. Thanks to everyone and again sorry for offended anyone.

You can even save the $ on the mods because most women do not like their cars to be modded and touched. The interior of the car is beautiful enough for them.

Again body kit wise most will already have the AMG kit, but some will change DRL's and add the odd spoiler. There is a good diffuser on offer, but again very expensive. Wheel upgrades come next and that is personal choice, again I think the Mercedes is a completely different drive to BMW so putting pencil thin rubber on is not a good solution particularly for women drivers..........

A tip on the SprintBooster that is not mentioned in the installation instructions.
Before installing, leave the driver side door open and allow the computer to go to sleep for about 10 minutes. If you have keyless go, leave the keys in the house while working on the car. The computer needs to be dormant while installing the SB.
A 10mm socket will remove the gas pedal. Simply unplug the connector and plug in the SB. You may need to slit the carpeting behind the pedal to allow clearance for the SB. Re-installing the pedal will cover any alterations.
Once installed, start the car and let it idle while the computer recognizes and learns the SB.
The SB normally defaults to the last setting on the SB. However, sometimes it switches back to OEM and I can immediately tell the difference in response.
Enjoy your off-the-line immediate response.
