Hey guys. I recently purchased a 95 9000cs. I've been researching the car and how to enhance the performance but I have a few questions for you. The guy I bought it from said the turbo was recently replaced with a used one. I just bought a boost gauge and each gear reads barely 5psi. I tried the basic boost pressure test and barely reached 5psi so tomorrow I'm going to adjust the actuator like I read. But I thought each gear, the psi was supposed to vary? I thought first gear was limited to a certain psi, and then it raised up as you changed into the other gears? I understand this car is equiped with the LPT and I definately want to change that over to the FPT. But I want to make sure I understand everything about the stock psi of the lpt first. One more question. I hear a scraping/grinding noise when decelerating. I have an auto tranny and it can be heard the most when decelerating from higher rpms. I'm pretty sure the sound is coming from the turbo. Is this a sign that the turbo is going bad? It still boosts strong, but only up to the 5psi like i stated before. Please clear things up for me. Thanks for the help guys.

and another thing

also, would the installation of an apc valve increase performance? Or does this need to be done along with an ecu from a fpt, same year, to show increase?
