Ignition timing related to boost?? Need help
 

So the supra started today and I decided to check ign timing. I jumped the two terminals and when I checked it it was way off like past 15 btdc so I adjusted the cam pos sensor via the little slot and brought it back down to 10 btdc and when I ran it it would only boost up to like 3 psi and then let off like that was as far as it would go but before when the timing was where it was at before I set it the car boosted fine like 7.5 8 psi. What's goin on here. Thanks in advance

Timing
 

Alright ill check it again to make sure. My timing light doesn't have a dial it just has a red button?? This could be like a reset button to calibrate the strobe to the spark. I also had two more engine codes pop up to. The first two I had was just the AFM code and throttle pos sensor code (51 I think). Now I have the knock sensor code and code 14 the ignitor code. But wouldn't my car not start at all if the ignitor was bad? I just put one on it from ebay cuz the old one was torn apart. Also before I set the timing I had intermittant starting problems and when it finally decided to start I checked/set the ign timing. Now it has started everytime after that but I've got those two codes and it won't boost over 3psi.
