Some comments that we hear from people are the issues with the Sniper system, when in fact, they are not first hand experiences. The truth is, there were some issues with the  injector connectors that have been corrected, as as well as changing to an external fuel pressure regulator. We have been using an original unit on our 500 HP LS in our parts van for years and it is one of our most reliable vehicles. We  would, highly recommend, recommend going to the new the new Sniper 2 if you are considering changing carburetor to a TBI fuel injection system. I, personally, guarantee that is the highest quself contained TBI unit on the market t! If you are looking for the next step up, we offer the Terminator series that has separate ECU and throttle body. Call me on my business cell phone at (910) 833-2312, and I will give you the HONEST ups and downs. We also offer compete standalone systems in Holley,Haltech& AEM for systems that support a few hundred to several thousand horsepower, naturally aspirated,forced induction and nitrous assisted engines, as well as transmission controlled operations.
