New ZDX owner here !

I've just become a ZDX owner for about 2 weeks. Really love the car but with 4500 lb car, i feel the car a little of under power. So i would like to order some stuffs from RV6 Performance to help the Z smooth out for daily driving. Any members here to know if has RV6 Performance had any promotion/ coupon code recently ? Please let me know !
Thanks all !
