Sprint Booster vs PedalBox

On a '07 328i AT.
I understand why these products exist now that I've driven my GF's car. The throttle calibration is not right, especially when taking off from a standstill. Using the DS mode all the time is too aggressive for her daily driving.

Anyone here with first hand experience on either of these products to recommend one or the other?

i have the same problem with my e46 m3. i find the throttle response too soft stock, and too sharp for daily driving on sport mode.

^i think Evolve has a tune that changes the throttle mapping/sensitivity.

I have INPA and DIS to interact with my BMWs. You'd think that there would some custom re-coding of the throttle available out there but I didn't find anything. $300 seems a bit steep to fix something that shouldn't need to be fixed but at least it's a "plug and play" type solution and you can re-use it or re-sell it.
My tendency is to try the PedalBox which is more flexible as far as settings even though the "Sprint Booster" has been around longer.

Haven't tried the PedalBox, but have tested Sprint Booster in E46 M3, so there was a big difference compared to stock. What I would say it's more sport oriented, so if You are looking for a daily driving, it might be little bit too sharp.

I had the SB on my 330CI with AT and with it set on the middle setting (green) it was great for daily driving. It definitely made the car more responsive, without begin overly aggressive.
I only used the red setting for Maxbimmer

I use a BMW PowerBox on my car (though will be parting with it soon in favour of a tune). It did a good job of reducing the throttle delay, and provide a bit of a performance bump too.

Works with all N52s, might be something worth considering. I especially like that you can adjust the setting from inside the car to adjust throttle sensitivity, as well as turn on/off the performance boost.

Good luck!
