The car is a 93 vr-4

1. on occasion when i stomp the throttle it sticks wide open and i have to either lock up the brakes or repeatedly stomp the gas pedel,what is broken that i need to replace?

2. my turbos make very little boost,they used to run very strong but now they wizz,this is my first turbo car,and i just figured that my turbos are just beat up and need to be replaced. is there any way i can check for sure without taking them off the engine

3. i have an apex'i S-AFC 2 and i know very little about it,but i do know the car has RC Racing 550cc injectors,why does my S-AFC make the car run like crap if i put it to "pressure" mode,it only runs in "karman",and what is Karman?

it also runs aweful unless i have the whole fuel map set to -15% or lower (i assume its my turbos again)

4. if my turbos arent the problem i think i have a genaric Greddy bov,it looks like the type-s BOV but it doesnt have any of the stickers (its plain purple on the top)

that should be it for now,thanks for any input,i really need it
