i am planning to put the racechip ultimate to my 35i xdrive, and the sealer told me that he can put this sprint booster to, so i think that the racechip alone will have a lot of better trottle response and lower lag, so i need opinion of someone that have this device thanks
and i see the Racechip have their own sprint booster to.
