I got RBturbos for my car 3 months ago, which is FBO. However, only 17.4psi can be obtained. So I got the stock turbo back and its also 17.5. I'm runing 100%meth and don't know why.
I'v been always using the 9-10 map.
Another question is the fuel economy. Its about 14mpg after I installed the Procede rev3. I find other guys usually have 22mpg. Its about 30city and 70suburben free way.I have 20mpg when I'm using all stock I swear I'm carefully driving, any suggestion?
