Can anybody tell me the name and the function of the shown sensors? throttle pic air intake pic

The first one is a throttle position sensor (TPS), the second one is the intake air temperature (IAT). It's usually on the air box, but with that intake it's been relocated.

Thanks for your response, I'm trying unsuccesfully to mess with the fuel cut  limit (0.5 bar) and besides fooling the boost sensor (zener diode) I dont know what else I have to check....

I don't really know a whole lot about the turbo car setups. But to help other people help you, what year/model/engine is in the car?

Also, do you have an check engine codes?

It's a 2005 impreza ts 1600cc with has been modified by the local dealership (light turbo kit, exhaust), the check engine light is off. I had the ECU remaped (unicia jecs) and fitted a lrger intake, but I cant pass 0.5 bar even with the zener diode trick on the boost controller

I know I answer my own question but in order to help others that have
similar setup I found out that the fuel cut occurs not by main ecu but
by a parallel ecu that monitors pressure via  vaccum solenoid. so boost
controller has nothing to do with it. I have been also told that over
0.4 bar is a no go with my current setup (I need forged pistons, oil
pump, gas pump, bigger intecrooler to reach 0.7 safely)
