you are still using the same distributor as before correct? If its a different distributor check in to the ignition control module or pickup coil. If it's the same 1 then you need to diagnose if its the injector driver or the wiring to the injectors.

Re: just completed a TBI to TPI swap but having problems
well someone will correct me if i'm wrong, at least i hope ,but i beleive the distributors on all late model efi applications 80-90s is the same on v8s pretty much. In other words use your old distributor and try again.
or if you would rather, pull your ignition control module and take it to the nearest autozone they can test it for you and that would most likely solve the problem.
if you still have a problem after rent noid lights from autozone and see if the injectors are pulsing ok.

most likely the easiest thing to do is take the module off and have it test most likely therein lies your problem
