Ok, so I got a BOSCH BPV and installed. Now I dont have the same noise as before. However, i think I'm hitting fuel cut???? In 2nd gear at WOT the boost pegs past the stock gauge limit and the engine bogs down. However, after letting off the gas, the car still hesitates and doesnt run properly. I have to nurse it along for about 30 seconds before it will just barely respond to throttle inputs without wanting to die. Shut it off for a minute and start back up and it runs fine until WOT issues again.
Questions:
1. Isnt the waste gate actuator supposed to open at 7psi? Should this not regulate the boost pressure to remain under fuel cut? I have not shimmed the WGA and there is no boost controller installed.
2. Do I NEED a boost controller?
BTW, I tightened the IC piping a lot more and its staying in place now. I didnt tighten more earlier for fear of breaking the plastic tubing. Didnt realize it had a metal sleeve inside to take a greater load than just the plastic would bear. All piping and lines are staying on now.....
