How can I get higher pressure for turbo
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? |

i think you can run those a bit harder then 17.4. maybe with a little more tuning and settings you should see 19 peak with meth safetly.
i would be dissapointed as stock turbos can do 17 PSI. |

You can go much harder, this is with a single meth nozzle and only 45% E85 (winter mix)...I can get more if needed:

As for the MPG this is the interesting issue you are having. Your stock MPG is low as well as your tuned which leads me to think you have a Hardware issue, possibly injectors or low compression on a cylinder causing the DME to bandaid something that is mechanically wrong in your motor. If its a bad injector that's the easiest one to fix and there are various ways to check for this. If its not a bad injector then you have an issue that the DME is trying to bandaid with Fuel, in this case more fuel than needed which drops your MPG. |

Are you running an RB map? Should probably bump up that overboost limit.
