I personally would go TPI and stick with it since you are installing it in a truck.
Stealthram will lose some torque since it is designed for more RPM.
I installed the Stealthram on my car a month ago and noticed a big loss in low end torque but since I have a car I want that upper RPM power band, TPI chokes at 4500rpm, Stealthram breathes to 5500+.
The sensors you choose will be determined by the year of the TPI setup you go with,
85 is the year you don't want.
86-89 is MAF, 85-88 have a9th injector known as the Cold Start injector and there is a sensor on the front of the intake manifold that controls it, it is the Cold Start Switch.
You can run an 89 Prom file in the 86-88 to eliminate the Cold Start circuit
Late 88 to 92 have VATS, so you will need to have VATS programmed out of the chip for the car to start.
90-92 is Speed Density aka MAP. 90-92 uses a different knock sensor than the 86-89.
90-92 doesn'tt use a separate ESC module.
If you have all the parts at the time of install, you can do the entire swap in less than 10 hours, this includes removing the carb setup, installing an inline external fuel pump, modding the fuel lines at the engine bay, doing the wiring, etc...
This is how long it took me to install my old TPI setup on a friends carbed Iroc a few years back.
this is what my swap looked like on my old 86 Trans Am,
