    I was wondering, if you use a boost controller is it possible to turn it all the way down to 0 psi. I know I'm asking a weird question but I'm curious. I'm the kind of person that buys a project piece by piece, such as a turbo kit, and I was wondering after I get everything and install it just to make sure everything is hooked up right and just so I know it runs, I was wondering if I could make it create 0 or even 1 psi without the computer going nuts or going into limp mode. I was reading that the ecu can handle a very small amount of boost without modification but I just wanted to ask the experts.

    thanks

    I wouldn't risk it. Why chance fucking up an expensive project? Do it the right way the first time.

    it's only because the closest tuning/dyno place around me is like 8 miles away and I don't really want to have it towed 8 miles but I'm sure I can get someone to do it for me

    Umm 8 miles isn't that far. Most people have to travel a lot farther than that to dyno tune their cars. Don't be so cheap, if nothing rent a U-Haul car trailer and use a friend's truck to tow it there.

    just unhook the i/c piping to the intake and drive it like that thats what i did it works just fine. then hook it back up when you get it to the dyno place. rep if it helps.

    You cannot lower the boost pressure using a boost controller. By lowering I mean you cannot run a lower PSI than the wastegate spring is designed for.
