I'm in the process of purchasing a MSD 5200 ignition box for my '89 R/S with the L03. I'm (obviously) not looking for any kind of horsepower machine out of this L03, but I'm wondering if this MSD box will give the car any benefit. A little more pep or fuel economy, etc. Is it difficult to install one of these? I just got a great deal on one so I figured I'd try it out. If anyone has any insight let me know. Thanks.
