Disable boost

Is it possible to safely disable boost? I read this,
http://honda-tech.com/showthread.php?t=170181 but I'm still a little confused. After looking at diagrams of waste gates.. they seem a little small to dump the exhaust effectively?
I'm thinking of a large valve that bypasses the turbo altogether and merges with the downpipe entirely, but I'm probably crazy.

Can you take the spring out of an internal wastegate?
Will that make no boost at all or just low boost? Thanks

Two things, why do you need to "disable" boost? Second you can prevent boost from happening by either disconnecting a charge pipe or unhooking the vacuum for the wastegate.

I'd like to run a small turbo on a B7 next year, but depending on the gas mileage I get with that I'd like the option to disable boost and switch to an N/A tune for road trips, or if I was having any mechanical problems I could disable boost to prevent worsening the problem, things like that. I might even want to only enable boost for track days depending on how easy it is to switch back and forth. I think it would add an interesting dynamic to a daily driver and wanted to know more.

Yea its not that simple, can't just undo something and run n/a then be on boost. Got to have a tune for it and its only going to run one way. Some cars once tuned on boost won't run at all with it "disabled", even if your car runs/drives without boost on a turbo tune you wouldnt be able to take it past 4k rpm anyway.

There are dual tune setups, just flip a switch and off you go. Or I could just swap the OEM ECU back in.
And you can't stay out of boost when a 14b or smaller is spooling at 1500rpm.. lol. I wouldn't be worried about it if I had a larger turbo, which I might still end up doing. I'm just entertaining the idea.

Idk about it, I'd consult whoever is tuning your car. If they say you're good to go on the idea then go for it. I understand what you're saying but it don't make sense to me atleast. From what I've seen gas mileage on a proper tuned setup on a small turbo still should see around 30mpg if you dont lay into it
