Some of the problem isn't horsepower, it is the "economy" and emissions programing that forces the transmission to shift into higher gears sooner and limit downshifts until you really mash the go pedal. So for Christmas I purchased her a download software package from O.E.Tuning, one of the vendors on this forum. She couldn't be happier and has mentioned several times how much it has changed the way the car feels. She says she has not used the sport button since. It's not some remarkable increase in horsepower, a lot of it is improving response to throttle inputs, seemingly the transmission included. Although I am sure paring down the ignition timing safety margin is a gain as well. I wish we had tried this on the E350 before taking such a haircut on the E350 during the trade. Consider this a testimonial, we really are that impressed the positive change in the car.

1 In the E mode I assume you still start out in 2nd gear.
2 How has that affected your mpg?
3 How did you get the download into your car?
4 How does this affect your new car warranty?
5 What was the cost?
6 Thanks.

1. I believe it still starts in 2nd, but I'm not sure, good question. We will confirm and get back to you on that one.
2. The mileage doesn't appear to have changed much if at all. Since the throttle isn't being pushed as hard to get the car to do what is requested, I wouldn't have expected much deterioration. She only puts about 6,000 miles a year on the car, so we really haven't had a chance to run a good long mileage check.
3. We purchased a "My Genius" O.E. Tuning hand-held programer, which was shipped to us. The programmer comes with instructions on how to log on to their website for the most up to date files for the intended application. You download the files into the programmer through your PC. All that is left is a 10 minute process to download the file into the car through the OBD2 port. The instructions are pretty good, but it helps to read them through a couple of times. And you really should have the car on a battery charger to make sure the vehicle voltage doesn't fluctuate.
4. I supposes that it is possible that a warranty issue could take place but it would be unlikely. They would have to prove whatever warranty issue you have was caused directly by the tune. I decided is was worth the very small risk as we have less than a year or warranty left on our car.
5. I would check with the different vendors as to pricing. What I paid 4 months ago may have little relevance today.
6. Your welcome, hope it helps.
The C63 gets huge gains with a tune because it is intentionally detuned from Mercedes. A normally tuned and naturally aspirated engine may have 15-20 HP left in it in most cases. A gain worth the 300 or so dollars on a Chevy but maybe not so much worth the 1000 bucks on a Merc.....up to the individual.
With a car like the E350, I'd just drive it and enjoy it. Tuning it is a little like installing big exhaust on a Civic.

if all you want is more throttle response then why not just run in sport mode for free?
I don't know what it would have done for the 2011 E350, but I wish I had tried it before going back a year with the 2010 E550.
