Review of OE Tuning's Tune On NA E550
The Best of Mercedes & AMG
It is a noticeable improvement, especially in the lower gears. Shifts are a bit more noticeable at times (probably from higher rpm shifts).
The car still hunts for 7th gear, but a bit less so with the tune.
Mileage, I was skeptical to see improvements but I think I'm getting 1mpg better.

We can tune to accommodate Sprint Booster, but a Sprint Booster is not necessary as throttle response is modified by our tune.
BTW, Sprint Booster does not add any more power, just fools the throttle signal to the ECU for a more aggressive throttle feel.
Thank you for the explanations, though. OE Tuning has a great customer service system in place. That is a great trait for a business to possess.
However, the sprint booster tricks the ECU into thinking you are giving it more gas than you really are, that's all it does. The difference with the tune is that the tune actually completely remaps the way the ECU picks up throttle input. Stock when you press down about half way on the throttle, you will feel the car SLOWLY building up power, that's because the throttle is opening at a slow and steady pace to maintain smoothness. After the tune, the throttle opens instantly thus you get a sudden burst of power rather than gradually.
Just my $0.02
With traction control off the car peels out sideways for a good few hundred feet. LOL!
What a transformation.
Oh and Kudo's to OE Tuning and thanks to Jeremy making this process easy and thanks for your help over the phone. You really can't beat this tune for the price backed by an excellent support crew.

For those that own Android devices, the complete process is far easier and more convenient than the MyGenius. But the tune is still loaded regardless of the flash system used.
