I would start with tps as the load source. It is scaled in #'s with 320= to 5 volts per the online instruction. Try and figure out what # = 1.5 volts and set that as your low tune point say 2.5 volt for mid and 3.5 for high.
Find a main scale setting that the car idles at. The set your low load correction at each rpm point up to about 3200-3500 so the car cruises around 14.7 Cruze is level road steady throttle position. Above that rpm set it the same or a little richer than the 3200-3500 point, richer at higher rpm. You will not really run at the higher rpm at 1.5 volts of tps any way.
Now work with the mid at high load settings. Forget part throttle boost for now, that's the hardest to get right. Pick a modest boost say 15-16 psi. If you start to make boost at say 2500 rpm and reach full 15-16 psi of boost at say 3500 you will have to pull fuel in this area. Example 0 correction at 2500 on the mid and high load point -7 at 3000 rpm and -15 at 3500 rpm. All ways start pig rich and lean it down slowly. Set your mid and high settings the same at each rpm point at this time. After you get it to run good at wot and get a better understanding of the unit, Later you can try and adjust the mid to improve part throttle.
It will likely run richer the more boost you run. (up until the point it runs out of injector and leans out, or fuel cuts.) That is why you need to run a consistent boost pressure and also why part throttle boost is hard to get right. Example If you tune the car to run wot at 15 psi, it may run richer at 18 and leaner at 10. At part throttle you may not be at full boost so it may run lean.
At this point i wound wire up the unit the way the manufacture intended. Using the set point voltages for baro and air temp. You can always try the baro and temp senders much later. And turn off all the advanced features like afr wide band tracking, Keep it simple till you get a handle on the basics. You will not achieve a the optimal tune in a week or 2.
