Remus Responder/Throttle Remapper
 

I've read a ton about Sprint Booster, but has anyone tried the Remus Responder or Throttle Remapper (the one with the LED readout)? I'm wanting to do something because even after a total reprogramming at the dealer I still feel throttle response needs to be improved.

I have three other cars with electronic throttles, including my E53, and none of them has as poor a tip-in feel as the E70. Hey, if whatever I decide upon doesn't make it drive better, it's going back.

They are all a total waste of money as they do nothing you cant do with your foot

Did you end up sending yours back?

I have never bought one
