2JZ GE VVTI NA-T VVTI issue

Good evening,

im having some issues with the CAM1 actual angle compared to the CAM1 Target table in my project. I am using the EMU black with a PnP Harness, 2JZ GE VVTI. 1999 Lexus gs300. As the title says this is an NA-T build and I have done everything that would need to be done to do that. Fuel system upgrades larger than stock injectors (550cc) BW turbo, manifold, intercooler, etc. you name it. I also had my engine block cleaned, decked and bored to fit new pistons and rods. Block was decked .009” (.23mm) and the cylinders bored .5mm over stock specs. Forged Manley rods and pistons. New tomei 1.5mm head gasket, head is stock, it was cleaned and added new valve stem seals. Adjustable exhaust gear, new VVTI gear, new VVTI solenoid. The issue I’m having is that when the car is started and is idling, and when it’s warm and idling the target for cam1 angle is 0°. The actual though says it’s about -9.5°to -10° retarded. DC% shows 2, even if the car is only in the on position and not started. CAM2 DC also says two but I don’t have two cam sensors so I’m assuming 2 must just mean it’s not being powered? I’m not sure about that. I can however make this cam angle change if I adjust the offset in the cam 1 parameters tab. Adjusting it up from 570 to 579 makes it stay at 0° give or take 0.5°. When I rev the engine and the target changes to let’s say 11° the actual won’t react right away and when it does it doesn’t quite get to target usually a couple degrees off. Would I need to do some PID tuning due to the changes I’ve made to the engine? And can someone explain what the cam offset actually is doing when I adjust it? I will include pictures for reference.

I would appreciate some guidance on this, I am watching the VVTI tuning courses now.

Picture 1 shows when car is idling and no changes were made. Showing cam angle is retarded 10°

picture 2 shows when I’ve adjusted the cam offset from 570 to 579. Showing that it makes the actual match the target

picture 3 is an example of how the cam1 actual angle doesn’t quite match up with cam 1 target, along with the DC reference.

picture 4 is another example like picture 3.

picture 5 is of the base map parameter settings for my specific vehicle. It’s no longer a “stock” engine so I’m assuming these all will need to be adjusted?
