    Idle overspeed underspeed

    Looking at my tune I noticed me Idle overspeed is set at -15 across the chart and my underspeed is set at 10. across the chart.The car is cam only (233/239 TSP).I noticed on other tunes nothing close to these setting. Does this sound correct?

    Does it chop hard?

    The car has a good rock to it. I am curious if these values seem correct?

    Is it normal to have settings like this? Most tunes I see have a gradual decline or incline in the timing change. ex.1, 3 ,5 etc.

    No it isn't, gets more aggressive as the rpm error gets higher.
