Hi all. It's been a minute since i last posted anything. Sorry, life gets in the way sometimes! I just acquired a new to me (my second) 1999 GMC Suburban C1500 SLE w/5.7L under the hood. It is running but needs some trans help (needs a trans swap) I realized after getting it home that it has a MSD ignition system on it. Everything seems to run fine. I am not familiar with this on a first hand basis. I do know they are more so used on street cars and racing applications. Since it seems to be working, do I leave it or should I replaced it back to stock at first chance? I dont need reliability issues and I dont know why it was installed. Any help is greatly appreciated. Thanks!
