Current mods airbox door mod, pair valve blockoff, naturally a k&n filter, new plugs & coils just incase but already installed full bricks exhaust and 08 fuel pump!

My issue is bike was acting like it had a vaccume issue so we opened it up found a couple of Mis guided lines and went back to tunning to run into an EXtreme lean issue I just replace the fuel pump because of this before anyone know what could do this maybe a bad sensor?
