Profec / EVC / VPC Question
Going back to my old turbo cars for a minute. I had the HKS EVC and Greddy Profec on a few of my cars. Is anyone going to be installing any of these on their 135i series? I understand many of us will go with the Procede as I myself plan to, I was just curious to see if anyone was going to go with a VPC or Profec in order to control the boost a bit better. High / low settings, overboost control, etc. Any thoughts?
