Msd Retard box

[FirstClass 383]

Has any one ever use a msd -8975 digital four stage retard box. Im going to run a 150 shot this spring and in stead of messing with the timing all the time Im thinking about getting this, I have a back that wont let me lean over for very long at all (being 67 ) and just trying to make my life a bit easier,when im at the track. any help would be appreciated truly thank's

I use the MSD 6530 and pull timing out when Nitrous is activated. Also gives me great control of the dizzy curve as well.

Or you can use a nitrous controller to ramp in and ramp out multiple kits or just one kit.
