Can you help me with my tuning?

[JasonZ]

I have the mods listed below. A few weeks back I ran a 14.9, I was happy, but I thought I could get even more before the next mod. I put FMS 9mm wires on, motorsport plugs, a new cap, and a new rotor. I gapped the plugs to .052 - .056. I ran the wires to where the crossed and touched the least, and made sure they aren't touching the headers. The car seems to be detonating and was before the wires. At least, I think it is detonating, from what I hear. It is just a knocking underneath the car, and I only have the timing at 12* on 93 octane. Tonight I put some octane booster in, and still I have the knocking. What could the noise be, and is it possible it is hurting my performance?

Lastly, I WANT A 14.7 WITH WHAT I HAVE NOW. I really want it, and I think it can be done before any other mods. I think my tuning skills are just not too good yet. When I check the timing, I took the spout out, and it seems to be mainly at 12* but every once in a while it jumps down to 8, what is this?

What else can I do to get my car to a 14.7? I want it badly. I took the air silencer out, put a k&n filter in, advanced the timing, got the mods below, I keep my engine clean, got the plugs/wires/cap/rotor on nice and new. What can I do? Please help. It will be greatly appreciated...
