hello, i need some advice on how i should run my car. okay, first i have a 91 integra ls with a b16 swapped into it with a drag turbo kit. i am also running the pr3 ecu. I've wired the three pin outs vtec pressure, vtec solenoid, and knock sensor. but for some reason my ecu kicks error code 22 (vtec pressure switch), which is making my vtec not kick in.i've switched out like three different pressure switches which i know work but still throws code. i heard of the mugen emulator chip which eliminates the knock sensor, 2nd o2 sensor and pressure switch. My friend acutally has one of these chips and when i put it in my car it runs like a champ. but i was scared of the all motor settings. i would get this chip but i don't want the fuel and timing adjustments that come with it( isn't the mugen chip for all motor). do you know of anyone who makes the same type of chip but for turbo settings. also i have a question about running the 2nd o2 sensor. my car is recently running not so good since i only have one o2 sensor.

what are my options about the o2? and any advice on making my car run better.

please help....thanx
