VMAX Ported Throttle Body review

I installed a VMAX ported throttle body today and I am very impressed with the improved throttle response and quality of the porting. I highly recommend them. I have an 2016 M7 and it has eliminated almost all the lag. I had purchased another stock throttle body from a forum member as a core so I could keep my stock one as a back up. It ended up saving me $100 going this route vs just buying one outright. I ordered directly from VMAX as I only live an hour away from them and had it the next day via Fedex. Their customer service it top notch!
