ive searched and only seen posts about the second turbo going bad, but i believe my first is the problem. here are the symptoms and maybe you guys can help me out. my car used to pull hard(2nd turbo) around 3200rpm's. but now it takes for me to hit 5500rpms before it pulls hard at all. anyone with any ideas? i have 130,000 on the turbos and in the process of buying a set of twins with fewer miles.(stayin with stock twin setup). thanks in advance for everyones help.
