Hi there,

I have my Silvia s15 upgrade and I have few issue with the engine at lower RPM (below 2000RPM). My car have EFR turbo kit from full race. The turbo is EFR 7163 with twin scroll manifold and direct line intercooler. I use Plazmaman plenum with 75 mm throttle body. The intake is standard Silvia s15 and using the Silvia s15 idle controller. However, I am using BC cams 270 Deg for intake and exhaust. The problem is when it is less than 2000 RPM it jerking and the power response very weak where the EFR lean out (above 16). It is a nightmare in traffic where the engine sometime can stalled. Also, when the engine heated up the RPM go up to from 1000 to 2000 RPM. Anyone have the same problem and share some thought.

Thanks
