how much of the engine can you monitor while driving? Do you have any way of reading ecu data live?

also, is it a mass air set up or speed density ?

Well the tps is wired wrong. When swapping dpfi to mpfi you have to switch the outer tps wires because it swings the other way due to the intake manifold design.

^ This.

If you're reading 100% at closed throttle and 0 at WOT then you don't have it wired right, no matter what the instructions you're reading from say.
