I need your help on tuning my car, I purchase a links g4 ecu for silvia s15 plug and play from supplier in Malaysia. it is silvia s15 with sr20det engine stage 2 modifications. It is installed with EfR borg Warner 7163 with internal waste gate. It have BC manual adjustable cams, 272/272 inlet/exhaust. We done the tuning with max 1 bar boost and achieved 370 hp. The problem I have now is running the car on street, I have problem driving the car with low rpm--below 2000 rpm, the car jerking not smooth. Also when the car starts to move, I need to rev the engine high to prevent it from stalling. So, can you help regarding tune the car to run smooth for the street use and at low rpm.
Thanks Mohamad muin
