I have put about 20k miles on one in my RV that came with it when i bought it and not sure how many miles the p.o. put on it but it,s been trouble free and runs / starts great.

THE one thing i don,t like about is that it,s not field repairable . If the internal module goes bad you have to send it to MSD for repair . They don,t sell a replacement module for it and they said you have to send it in for repair if you have an issue .
