Hi ZTHians... need some explanation regarding how a Throttle Position Sensor (TPS) relates to Ignition Timing and Fuel Pressure (Fuel Injection).

Having headache trying to figure out matching the setup properly to get smooth running on my 4G92P. Just recently plugged in Works 70mm throttle body and trying out Piper's 286 cams, but having bad jerks when throttle is opened below 5% or below 2000rpm before a go, and I miserably lost all the torque and bhp I had before...

Just to make it...
