Guys in second gear my car occasionally detonates. I have a 255 in tank walbro, new fuel filter (in line under car in an 86), plus cleaned and flowed injectors. I did install a used kirban fpr. Is there a chance that the fpr is going bad?
What did you set the Kirban to and is it performing as it should under boost?

fp is at 45psi with vaccum line disconnected. Shows 36psi when connected. Car pretty much runs rich after boost or at start up. My boost kicks in early because I am running a .48. It starts to ping in second and I let off briefly and hit it again and spike goes away. I feel like if I keep my foot on it that the spike will get louder and worse and "Pop goes the weasle".
Is your ignition tune up stuff in good working order????
