Quick question - are you sure you sent your informal discovery request to the right CHP Office?

CHP has many offices throughout the state. Each office maintains its own records and has its own Custodian of Records independent of the others. If your request was sent to an office different that the one the officer worked out of, then they would have nothing to provide you.

Look on your citation for a box marked "AREA". It should contain a three digit number. Let me know what that number is and I will tell you what office you informal discovery request should have been sent to.

As a side note, I will offer the following observation regarding stop sign violations. The law requires that you come to a full and complete stop. Most people depress the brake pedal causing the vehicle to slow until they feel it lurch forward. Based on that lurch, they honestly and truly believe they have come to a full and complete stop when in fact, they have only slowed severely but are still rolling. They then continue on their way and are often cited for the violation. It is only when they feel the car lurch forward and then rock back that they have come to a full and complete stop. Most people miss that.

When you get a chance, go by a busy intersection with a stop sign, sit there for a few minutes and watch. You will see what I mean. The easiest way to ensure not being cited in the future is to hit the brake, feel the car lurch forward, wait for it to rock back, then count to three before you proceed. There will be no doubt in the mind of any officer monitoring the intersection that you came to a full and complete stop.
