MSD #8981 Programable Timing Computer, will this be as good as a MSD BTM to work with my Charger. Would it make a diff if I was pulling timing at boost or at rpm?

I like the BTM. Your boost will not always come in as rpm increases. Load plays a big factor and so does weather. Colder air = more boost. Also, with the BTM, you can calibrate it and actually see that it is working.

Thats what Dan said, and I was thinking the same. I just got one from E-bay. I really don't want the charger, but if I can get it lined out it may be a good thing.
