hello how are you
i am from saudi arabia and i own a shop

i saw tunercat software and read about it
what i know is that tunerat will offer me the dealer kit version for 325$ shipped and i must buy from jetchip the DST tuner for 499.99$ and i dont have a problem doing that but it comes with 4 license that i dont know what is the difference between it and between VDF from tunercat

the vdf i will buy from tuner cat are for 07-14 e38 and e92 controller and should i buy the TCM vdf if i only want to use it for speed limiter ?

thanks
