    I've been using the website for a bit, has been very useful to read other's experiences to give me ideas on where to start. I have recently put a lot of work into my 1st gen speed 3. The largest item was swapping my factor replacement turbo to a BNR v3 Stage 3 turbocharger and an accessport from Cobb. Was doing just fine until I ran into a overboosting issues, should have been about 16.5 psi based on tune. However was getting up to almost 23 psi of boost, the vacuum line on the cold side of the turbo had popped loose. Then began the lean running conditions. I had followed some forums and was talking with my mechanic just to think of somethings to look at. Within the last few weeks I had changed out some OEM parts on my car to attempt to solve the lean condition. Started with changing out the purge valve solenoid, and double checked my intake pipes, my boost tubes and intake from turbo to air filter. Afterwards, it had became worse. I had then decided to check my PCV valve, had issues with it last time I had overboosted. Them most recently, I installed a Damond Motorsports PCV plate, replaced gaskets to get to pcv (intake manifold, throttle body, egr return line) Corksport boost tubes, Corksport EBCS, Corksport 3.5 bar MAP, new Denso MAF, and installed OEM replacement crank vent plate gaskets and PCV valve hose. After all of this, still having issues with my AFR's being very lean. attached is a short drive around my apartment complex, too worried to actually drive it.

    Forgot to mention I added a GFB bypass valve, bought the car with Corksport 3 in. power series short ram intake, Borla cat-back exhaust.
