Racechip XLR or Pedal Commander?
I’m looking for a little more responsiveness from my 2011 E550. With that in mind I’ve been considering either the racechip XLR throttle tuner or the Pedal Commander. Can anyone speak on their experience with them or give a recommendation?
Thanks for any help in advance!

I've researched it and have a decent understanding and the crack is to achieve an old school 1:1 drive by cable relationship with the throttle plate .
There was nothing wrong with this arrangement but like the old mechanical handbrake the boffins like to mess .
A car with a drive by wire throttle lag delay has the best results .
One without and the gas pedal may become too sensitive , but given good foot modulation and the range of settings I still find this difficult to comprehend.
The controller and wiring for both products is meaty to say the least but with the original inventors product the dimensions are miniscule and can be disregarded completely with a last setting memorised for a completely stealth install .




Cost $300 for me many years ago. Probably still close the same. I had it in my 2011 E350 and have in my current 2010 E550. It has plenty of settings including OFF that disabled it and car drives like it was never installed.
It has Green range 1-9 and more aggressive Red range 1-9. I have mine on Red-3. I feel higher is too aggressive.
Best money you can spend on the car.
Just checked. Sprint Booster is $289.99 so they lowered pricing by $10 since I got mine.
