Car started up easily. Idle was lumpy at first but the fuel rail and injectors had not fully pressured. Once fully pressured, idle stayed around 900 RPMs. The engine stayed very consistent all the way up to when the fan cycled. It does idle unbelievably rich. I imagine that is normal for a port injection starting point. I did not pull the car back up the driveway. I coasted down out of the garage and started at the end of the drive before starting. I did not want to flood the house with exhaust air there was any heavy exhaust. I put the car in drive to pull it back up but it stutters then goes smooth. I put it in neutral and touched the accelerator. The car will rev freely then stumble at the idle point before cycling between 900-500 rpms multiple times before smoothing back out at a steady 900. I just shut it off and left it at the end of the driveway.

Car pulls amazingly and continues to pull into the higher RPM range. Just wanted to see if there was any more headroom in the turbos. If so, would we be able to add any more or do you feel this is the top of what is available?
