92 octane and lately the car is pinging when under load. I think the fuel system is fine but I don't have a walboro pump. Maxing out at 10 psi of booste with no intercooler
Wondering if wires could be the problem. I have had some NGK blue wires in there for about 100 000Km. Do they wear out?
Pinging at max booste any ideas

I have been running the car like this for a while now and it never used to ping. When I say max boost is 10 I mean it sometimes spikes to 10. Normally full boost is around 7-8 and it still pings.

Changed gas lately? Running premium?
CHECK your plugs and wires. Make sure the plug wires are secure.

spoke to the stealership because no one has wires for my car and they said that wires wouldn't cause pinging.
Also I do have a newer knock sensor. What if my fuel pump doesn't have enough pressure. I did replace it once but with a cheap one.
I will start looking for an intercooler!!!

just checked the resistance of the wires and coil and they are fine. I am going to pull my injectors and have a look at them. Maybe soak them in injection cleaner. I am thinking my problem is fuel now. Also found an intercooler from a saab 900 for 100$ at a wreckers. I will turn the boost right down until the pinging is gone I guess. Any other ideas what might be the problem. It is pretty hot here right now also.
