open wastegate?

Ok so i want to start building a diy turbo kit, my question is this since i need to build the kit first before i can get it tuned, will i be able to drive the car if i leavce the wastegate open? i will probably have to drive about 5 hours to a tuner. what amount of boost would i make if any? i will also leave the stock maf and injectors in until the tune is done.

i did not mean unhook the vac line from the wastegate. i thought that on a internaly wastegated turbo if i unhooked the flapper from the actuator and kept the flapper open, it would keep the turbo from spooling, am i wrong?

run the turbo but leave the charge pipe off, dont change the injectors, and run a short ram intake with the stock injectors in and let the boost just go to open air.......then when you get to the tuner swap out the injectors and connect the charge pipe. then tune away

Wouldnt do that either , can over spool and is bad for the tubo , leaving the waste gate open would be way better than the boost side

Put a 5 LB spring in it and some 100 or better fuel and drive it there

that would still cause it to overspool because of the turbo not getting any signal of boost pressures. Light throttle and a light wastegate spring should do the job
