Racechip Tuner is the XLR Throttle tuner worth it?

Getting ready to buy the Racechip RS tuner for my 2015 Z4 28i. They also offer the XLR throttle tuner as an add on. Anyone running both of these and is it worth the extra $$$ for the XLR?

Thanks, Corn

I successfully installed the Racechip tuner tonight. Glad I didn't pop any codes. Will have to wait until tomorrow to see if my butt feels any change. Haven't installed the pedal box, yet.

UPDATE:

Installed the pedal box. Wow! What a difference. I now have the Z4 I always thought it should be. I set the pedal box to sport+ and that seems to work great in comfort mode and sport mode. Just right.

Congrats on the tune and pedal box. Did you do any before and after dyno runs?

So for 1/2 the price, you can purchase MHD, and have upgrade options. They are both effectively remapping the throttle and changing the tables to allow for more boost (HP)

That's fine if you want a flash tuner. I did not.
