I'm saying take a look at our articles as it may help you out in getting the motor running right.
You also didn't answer my question. When you put the manual TPS on, did you check to make sure it was properly installed on the throttle body. An improperly positioned sensor will give funny readings and cause a stumbly idle as well as driveability issues.
The stock redline is closer to 7200. It's a moot point given that your car isn't running right, so I don't know why you're running it up to redline. Redlining isn't recommended even on a normal running car.
Since this is an S14 motor, I would double check that all of your wiring for the VTC is done correctly. I could see the VTC frakking with the base timing, causing some of your issues.
