engine has 4.75 quarts of mobil 1 synthetic oil
70k miles with no previous problems
running premium gas
boost is at 4-5 psi
i havent had a problem since the install last thursday, knocking was always 0-3, but recently it has spiked up to 20 at times. i was wondering if it was normal, and if not, how i can fix it.
thanks
wish I could help, it sounds like you shouldn't have a problem vbecause you're running such low boost and it has such low miles with no previous problems. Maybe some bigger injectors are needed?

shouldn't be a problem. mine can go up to 30 when the engine is hot and I get on the throttle. what are your base knock settings? there should be one for 2500 rpm and 5500 rpm if I remember correctly.
yeah, for running boost, thats low numbers, i wouldnt worry unless the numbers get higher and stay high
highest i got was just a little below 100, but that was at 8psi and WOT, and even then it was only for a split second then dropped to below 10(numbers skyrocketed the day the fuel pump gave out tho, 150+ sustained)

What exactly is this measuring? Im not experienced at all with the safc2
More importantly, what base timing are you running and when do you get the knock? Is it only at WOT or idling? Its normal for me to see values in the 8-13 range when the engine is really warmed up and is idling. I think its just hearing some of the internal noise of the engine with 130k of wear on it. Its not actually knocking at idle.
I would try dialing back the timing some, if it goes away, then it was actually knock and you probably had a bit too much timing in it. Also, when did you calibrate the knock monitor? The engine has to be really warm when you do it. I would say at least 30 minutes at highway speeds.
