1) You should not have any knock below 15 psi boost alky or not. So while your mashing the pedal your not telling us at how much boost & what is happening.
2) If your tank is low on gasoline you might be leaning it out. If your fuel pressure drops when going into boost.. you will see knock. The Xylene maybe band aiding it.
3) the Alky kit works directly off of boost. The LED going red to green while that is now an issue, I don't know that is the issue especially at lower boost levels. One thing I suspect is the "Initial" control inside the PAC box may need to be increased a touch. That will put a little more power to the pump. So if its at 11:30 move it to 12:30. And make sure the ground to the controller is solid.
4)If your BL numbers are below 128 idle/cruise you probably have too much fuel pressure. I usually set fuel pressure to see some numbers above and below 128.
5) You should get a fuel pressure gauge and put it to the windshield so you can confirm every lb of boost your getting a lb of fuel pressure. So if its 43 lbs line off.. at 15 lbs you have 58 psi fuel pressure. 20 PSI you have 23 lbs. if at 20 psi you have 58.. your going to get knock.
