Finished putting on turbo and when I start the car it sits around 19 afr when we were trying to tune it and add fuel to get it to a normal afr the idle would get very rough and sound like its flooding the engine anyone know what the problem can be

 

Can't help without knowing more about the setup. I'd think your tuner would be more helpful here.

 

Maybe you have an exhaust leak ahead of your A/F sensor that is pulling outside air into the exhaust system corrupting the A/F values.

 

Have you tried using a base map?

make sure the parameters are correct for the fuel injectors, dead times and injector size with the EMS you are using.
