From what I've been reading, every motor is a little reads a little different (especially modified) and with the stock sensor you have to 'learn' what is a safe reading and what isn't. I don't know what the truth to this is though.
To solve your problem, so you don't have to rely on tuning with the stock sensor, rent/borrow/buy a 'knock box'. Then you can tune without worry, and also find out what is normal for your sensor.

Holy shit, low 8s?! That's SUPER low.
Ok cool, I'll check out the knock box. I know our stock sensors are pretty bad about crying wolf, so I'll check this out. Thanks!

I don't know the exact numbers yet, but the bar looks to be all the way across at cruise AND wot, so I'm gonna say AT LEAST 90s
. I'll have to adjust it to read numbers instead and then I'll get back to you.
