MSD rpm pills?
Are these pills the same (other than rpm)? They all look different.
Will they still work?
(the middle one is MSD not shure of the other two)
Allso what pill should I use for my window switch for my nitrous? I normally shift about 6800, but I couldn't find on I have 6600, 7000. I dont want to miss a shift and over rev it!
