Recently, I have been getting KR on my 87 WE-4 at 3/4 to full throttle with the alky on and boost set to 20 psi. I disconnected the alky and turned the boost down to 15psi, and I still have KR. I am pretty sure that it is not false knock, sometimes it is audible. Any ideas on where I should start? My car has a hotwired Walbro 340, Accufab adj FP reg, adj WG actuator RJC powerplate, Kirbans 3" DP, gutted convertor, DIY alky, RA 93 chip, and a K&N open element. It also has a new AC Delco PCV, AC42 TS plugs gapped to .034, Coil pack and Ign module, ECM, Map sensor, Maf sensor, and Magnecore 8.5's. I don't have Turbo link or Direct scan, but I do have a scan tool. Thanks in advance.
