What year?The new 496's with the 555efi is hard to program.Whipple is the only one.Most are changing them over to Mefi4

If its mefi 1-4
It can be remaped, Just depends on what you do to it, if it really needs programing.

I also recomend Mark at Precision Marine ,He will tell ya if it will help.no bs

If you are going to change cam and do head work then I would change over to a Mefi 4B we do it all the time. You also need to change the sencors.
