i have a jdm b16a2 with a t-3 turbo 12:1 fmu for fuel and running 5psi with a greddy intercooler. my problem is it seems to bogg after the car warms up.it will take of pretty quick and then a second later it boggs down.it only does it when the car is warmed up to operating temp so i'm thinking that it may be caused by a bad o2 sensor. can it go bad and not throw a code?i did however throw a o2 sensor code a while back rite before i had the engine rebuilt but it has not returned since.if it is the o2 sensor that would explain it all because doesn't the car run in closed loop (i think that is what it is called) until the car is warmed up? also my air/fuel gauge is stuck in the rich position (all wires are still hooked up properly) so if the air/fuel gauge is seeing a rich voltage so is the ecu.so that would cause the ecu to try and correct a rich condition when it realy is not and then causing a lean condition because the o2 sensor doesn't change the voltage(?)anybody have any idea's thanks oh the ecu is from a 93 gs-r

Checkout your fuel pump. That did it for me.

when under boost the fuel gauge reads 90psi. what did your car feel like when it happend? was it through the entire rmp range?what was wrong with your pump? thanks
