Sprint Booster vs Adaptive Reset
So, I tried the "sneaky ecu" reset on my 2010 E550 and it made a huge difference in throttle lag. Of course 2 days later my car relearned my driving habit and is laggy again. I can't help it, I don't have too much open road around me. So, my question is, should I just do the ecu reset as much as possible or do I buy a sprint booster?
In other words, after much reading, I am under the impression that even if I buy a sprint booster, I will still have to do an Ecu reset once in a while. In that case, I rather just do the weekly reset.
The sprint booster takes out throttle delay but what does it do when a car relearns granny mode?
I hope I wasn't too confusing!!

Interesting question. Don't have the booster myself - I just do the ECU reset whenever the throttle response bothers me. Makes me appreciate the difference.
If you had to still do the reset with the booster, then what's the point.

Anyone else using a sprint booster?

SB does not do anything to transmission - its eliminating the dreaded throttle delay. Its been covered in great details in many places. Search will get you all the info to help make your own decision.

Just noticed you have '14 E550 too. I have no issues related to needing to "adapt" or any throttle delay (doesn't "tune" suppose to eliminate all "that"?). In general I found that facelift (2014-on) E cars do not suffer from throttle delay exhibited by 2010-13 E models and do not need SB. I used SB in three different Es (two 350s and one 550) prior to facelift, but not in 2014 as it does not need it. However, I do need to use SB in other 2014 models, like CLS and ML (I did not drive facelift corresponding models, so maybe it was "fixed" there as well).

For my 2010 e350 it was wonderful and gave me the responsiveness I felt was missing with the standard throttle. However, with my 2014 e350, I found it to me unnecessary and I sold it on the site to another 2010 owner.
