I installed a MSD Atomic unit about 4 years ago, drove it many miles, probably 10K or so. Always had problems with it, never could get it sorted out. Talked to the tech hot line guys many times and if I could have reached through the phone and grabbed a couple of them I would have. Anyway, it came down to the fact it was now dangerous to drive. Stalling on de-celleration, so loss of steering and brakes, just when you needed both. Some guys swear they have no problems with it, coming from MSD's web site comments, so take it for what that's worth.
So I pulled the trigger on the Sniper, another $1K out the door. But really good carbs. are at this price range or close also. After the install with a mag pulse distributor and timing controlled via the Sniper I went for a test drive. Wow! What a difference. This thing gets up and goes!
It comes with software that allows tuning with basically unlimited possibilities, requires laptop, or you can just use the basic self tuning via the handheld. Your choice. I have experience tuning with highly modified tuned port injection systems and the software for the Sniper is top notch. The learning curve could be steep for those with no experience, but well worth the time to figure it out.
So if you are thinking about it, my vote is for the Holley Sniper.
