Hi,

I had a thread up about my Evo 7 boost, it's only boosting to 0.7 0.8 max.. Iv looked at the pipes from turbo to actuator to solenoid etc, they all seem fine. What should I eliminate 1st?
The engine light also, had a computer plugged in and what was showing was
P0170 Fuel trim Bank 1
P0400 EGR 'A' Flow


Please help.

I didn't find the right solution from the Internet.
