Yes the timing in the programming can be checked and changed if need be but not with insite, you need C A L T E R M for that.

A word of caution though..... 870 ECM's are well known to brick when flashing them. If you don't know what your doing you could end up with a truck that won't start.

Runningrough use to do all the 870's around here but it seems he's MIA lately, you could try sending him a PM.

This ecm is new to me it came with the core so I have no information on who tuned it or anything of that nature. I’ll send him a PM thanks
