The boosted guys he is talking about are LS1 guys. It's alot easier to convert them to a 3-bar speed denity tune custom OS. Our pcm's are only setup to go to 140kPa (~6psi), and you'd have to mess with a custom OS (doubt anyone's successfully done a 3800 with results yet... I was shown the space in the data on our pcm's, and there's not enough in the VE's current location to add many lines beyond stock, so alot of re-directing would be needed).
