Was running a little sluggish and thought I was running out of gas. Since then I’ve changed Fuel filter, Plugs, Wires, Distributor, Rotor cap, Coil and now the TFI module. Still slightly misses and has a pinging sound

Well, First off anytime you hear pinging this is an indication of improper ignition timing or low octane fuel. Low octane fuel can be cheap/bad/contaminated gas. I would try a bottle of Octane booster first and then buy some higher octane fuel at a different fueling station than you have been using and see if that doesn’t take care of it before going any further.
