Just saw this on another forum, that someone I trying one of those plug in boost controllers. He said isn't wasn't made specifically for the SHO, put was ask to try it. Probably for the F150's. Says his car is tuned. I saw another vender was selling a module for the F150's and says not to use with tuners. I'm afraid something bad is going to happen with these. From what I have read all they do is modify the boost signal to the computer. What do you guys think.
