CSX3170 Engine problems

[Cobra #3170]

I finally got the bugs out of the system and the engine works as it should huge top end power and great low end response and drivabilty.
The problems were related to low voltage at the computer because my alternator had an open diode and a burned winding on one of the output circuits. The master disconnect was high resistance at 30 amps but would still start the car. I was loosing 1 volt there, at times the voltage was so low it affected injector opening time and duration. I shunted the stock amp gauge by installing an 8 gauge wire between the starter solenoid (battery) and alternator output terminal.
I still get readings on the amp gauge but not so large as with the stock set up.
I also had a defective 5 wire O2 sensor and after fixing that found that the engine map was really lean between 1400 and 2500 rpm with small throttle angles.

Here is a video of an autox today, unfortunately the mike battery was dead so hardly any sound which is the best part. My driving is not so hot either, way too much steering input but that can be fixed with practice.
