Should I get a high performance torque converter?

[Ryansal]

Hello All, 

 

I have a 2018 5.3 silverado, currently have a 6.2 manifold and throttle body, cold air intake, new thermostat, (had high performance plugs until they started misfiring now back to GM), Borla dual exhaust, american racing long tube headers, and a tune.

 

I have a 7" lift with 35" tires.

 

Besides a supercharge or turbo I heard there is not a ton more I can do besides a high performance torque converter.

 

Any suggestions or advice on this would be very much appreciated, thanks in advance.
