Sprint booster worth it?

I bought it for just the drive by wire throttle pulling out delay - safety .

The rest is a bonus .

Regarding questions not answered, you’ve never once responded to the question about contacting Mercedes about the dangerous (your words) throttle delay.
As you’ve made it clear that it is a serious safety issue (to you) then Mercedes needs to be informed.

I'm not going to complain about an issue I no longer have !

I hope you've notified your insurance company of your modification...

Yes , LK no charge as it doesn't add bhp .


Pedal lag is common as..

Yet with three MBs I have no lag.
And neither did the previous 3 I've owned.
Maybe I'm just better at pressing the pedal further...

You highlighted a serious safety concern but not to the manufacturer?

Instead of helping others you want to perpetuate the selling of a solution rather than fixing the issue.

I really don’t understand why you are so fanatical about your box? Are you on commission?

Different cars have different delays and some none at all , a 2011 Q5 2.0 tdi with S-tronic had a big delay where's a 2014 Q3 2.0 tdi S-tronic didn't and the ones with the biggest delay get the best results .

You'll never get anywhere with manufacturers , did VAG recall the infamous 2.0 tdi 77mm oil pump drive that would lose drive , oil pressure and seize an engine and goose a turbo .

Must be.
Every technical document I can find describing it's operation (including some retailers in the US) describe it as being an amplifier. As it's an amplifier and has a range of 0-100% it cannot do anything more than moving the pedal further does. Simple physics and science with no unicorns, fairy dust or magic beans.
Throttle filtering is done in the ECU, not the pedal so any filtering by the ECU that may cause lag is still there.
If course people may fit one of these, move the pedal the same amount as normal and go 'Wow no lag' but that's only because the effective throttle opening is wider for the same foot movement. Learning how to press the throttle pedal further would accomplish exactly the same thing.
These tests where a switch is used to compare are fallible as you need to operate both channels from the pedal (there are 2, typically 0-5v and 0-2.5v) which operate together. Unless you switch both signals together you will get delayed response (and probably an ECU error).

Now as I've said if people like them great, but don't try to suggest that pressing the accelerator pedal harder won't achieve the same thing as the physics and logic doesn't back that claim up.

Not with that attitude you won’t.

If everyone gave up before they even started we’d be in a very sorry state.

You could have taken the advice you were given over 12 months ago but you didn’t and chose to buy a pedal box instead. You now evangelise your box as the one solution to a problem that isn’t an issue for most drivers. Perhaps you’re trying to justify your expense.

I see your box the same as I view the Kardashians. In that they are a fix to a problem that doesn’t exist but lots of people like them anyway and give them lots of money.

DVSA is equally as incompetent as a limp mode that loses power , power steering and brakes is not an issue because in their utopian world everyone on the motorway keeps the safe distance .
