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.
