2012 2.0 coupe trouble shoot


Hasn't posted much yet...
Hi guys. So I have a 2012 genesis coupe 2.0. I blew the motor and my mechanic said a 2013 engine would be a exact fit and would be beefier so I agreed. Since then the car doesn't run right. The car has aftermarket turbo, intake, intercooler, turbo back, and a pre tuned computer for a 2012. Can anyone help me out or at least head me in the right direction. Thanks
