My roommate gets mustang magazines monthly and I paged through and found this article. 5.0 mustang & super fords Feb 2004 issue has reviewed the plasma booster from ignition solutions for the mustang. they state" The PB helped, though, just as it had in our previous testing experience, and any power from an ignition is impressive. It boosted the peaks by 3hp and 2.2 lb-ft, but it picked up power across the board. there are no dyno's but they posted a chart of the power and toeque in different rpms. for those of you interested check it out. they also tested other mustang components and checked for different gains.
