Why do people adjust boost depending on their driving conditions? I see folks say they run 7psi around town and 20psi (or whatever) at the track. Why not just set it and forget it? If you have your car tuned for 20psi and don't boost it around town, then it's no different than if you had it tuned for 7psi. I don't get it. My car is tuned for 10-11psi right now and that's as high as I can go before fuel cut (I'm on a stock ecu, no piggy back or FCD) -- so I just leave it regardless of how I drive it. Why would I mess with it and reduce boost for just "driving around town"?
