I recall that they had ads out touting some magical power increase but I always doubted that. The one I got made zero difference in performance compared to a MP orange or Chrome box.
Power increase is probably more noticeable over a stock ignition when going to the Rev kit....the other performance ignitions are probably similar in performance but the rev-limiter is the main difference. They also say all the parts are made in the USA. I like mine, works good, I installed it after my MSD 6AL went out. Their place is about an hour away from me, I need to visit their cool mopar shop some time, Troy and Laura are awesome peeps!
