Looking for some direction or a website that can help me setup my 87GN. It has seen very little use in 3 years and I now want to play again. I’m showing timing retard in Scanmaster in the 10.0 to 15.0. I have good fuel, boost is down to 12, fuel pressure is at 60 WOT and chip is set for 20 timing with 93 octane. I have also run carbon cleaner through and still having problems. I have changed chips but it does not help. Injectors are new 50#, fuel filter is new, sock is new, and both pumps are working. I have replaced wires and plugs, which were slightly oily and fuel smell. Also the fuel smell with the car running is very bad. Any steps to work this through would be appreciated.
