It's not very often that I've seen a clogged injector. I may have missed some of your post but are you getting a lean code in one of the banks? If so, try switching the injectors on the left bank to the right bank and then see if it throws a code for the other bank.

Check for dirt on the injectors tip. There is a small metallic disc with tiny holes on the tip. If tiny holes are clogged with dirt, maybe the injector has to be cleaned or you can replace it too with a new one.

Make a WOT pass, stop and check plugs. If you have brown plugs and white plugs, fueling is bad somewhere.

Also Check compression, leakdown. Maybe the previous owner washed down cylinders with a bad tune (too rich for a long period). Are the camshaft sprocket and crankshaft sprocket dot aligned? Ignition timing good?

This car should burn the tires even with 3.42 and Nittos

Thank you everyone for your help. I swapped out the springs with the Patriot Gold kit and it no longer appears to be smoking when I crank it. It also is running much better...spins first and part of second now lol
