Msd Racing Ignition
Unless you have severly modified your engine, it's not needed. It would be much less expensive to get somekind of engine management and advance your spark a few degrees with your current coil pack, probably same gains but with the possibility of doing other configurations. Besides, it's only noticeable if you have a ton of mods OR are turbocharged, in which case you could want that to retard spark and avoid detonation, but again, a mangement system would be a wiser choice.
Ok.. it was a topic about this a few weeks ago... but its like Zman said, its excellent only if you have Turbo, NITRO or a very serious modifications... This has a high cost ... around $400.00 on MSDIgnitons... (you can get it Less expensive on EBay) You can expend those 400 bucks in a lot other minor modifications...
