People... Don't post when you don't know what your taking about. That car probably won't even run if you slap 750's in and start it up, the stock injectors are ~440 cc. That's nearly injecting double the fuel if you run the stock map.
What you need to do is email/call the tuner and tell him to make you a basemap for those injectors. Then flash your ecu with the basemap using either an ap or a tactrix cable and drive to your tuner out of boost.
Good luck, looks like a stellar build. The turbo parts you have are all pretty simple to install with the help of diy's on here. Save yourself the money
