ugh. maf/tps issue

[JRPS13]

so basics...

jdm 180. sr20det redtop
gt28... stock ecu injectors

so i was rollin on the highway on sunday, went to boost my car, car ran good. went to do it again and the wastegate wouldn't open up.... figured i blew the line off the wastegate.
got home nope line was good...

figured it was the maf, replaced the maf... same issue....
was bootin around to see if i was hittin boost at all and i would get like 3lbs and id hit fuel cut.

so i ran some voltages on the tps. and a diagnostic. got code 43 - tps. changed out the tps. code disappeared, and i got 55, healthy ecu....

car still hits fuel cut around 2500-3000 rpm.

only thing is i can get the tps at .47v max at idle/on position.... and only 4.1 wot. reads .45v at ecu and 4.09 wot at ecu.

however my maf only reads 1.8V or less at idle.

i figured my throttle body may need to be replaced since i cant get a full 4.5V at wot. but now that i cant get 5v at my maf im stumped.

think my ecu took a s***?
or did i just get a fcuked maf again?!

much help is much appreciated

thanks!
