Car breaking up!
Hey guys, I have a gte motor in my gs300 and I put new plugs in it and it drove fine. I let the car sit for about a week then I took it out to drive to an event and she was breaking up badly. She was doing this prior to the plug change, that why we changed them. Well my shop looked at the car again and said my car is breaking up under partial throttle. They said the AFC couldn't compensate for the richness that she have doing this moment. They told me maybe I should look into a better fuel controller like a Map ecu, or an AEM ecu. What do you guys think, I am tired of this braking up crap. Car have twin walbro pumps, AFC (1), VPC, GCC. When she breaks up I can see the AFC throttle sticking,and some time the rpm stick to(both on the AFC). I am thinking about the Map ecu. Who running one? I searched and couldn't come up anyone that using one on this board.

I am a casual observer having no experience with the JZ motors, but having read much about various set ups on both the 1JZ and 2JZ.
I have seen dozens of set-ups in the ballpark of your power levels with very simple fuel management set ups. I definitely think you should be capable of 380whp and good street manners regardless of rpm with a simple piggyback.
Others with experience need to chime in here. I am just speaking from my recollection of set ups that I have seen on supraforums.
