So I just received my new 4150 Stealth system. I ordered the Demon throttle and kickdown bracket (#1953) as per the instructions. Well, this bracket doesn’t seem to be the one for the Stealth throttle body. It has two mounting holes for a dual pattern type setup like the Street Demon or original Sniper TB. This works on the Stealth, but apparently not on the original Sniper. Holley didn't do a very good job with the supplied documentation, as it seems my Stealth 4150 came with instructions that are meant for the older Sniper systems. The online instructions are no different. The Demon 1953 is definitely not compatible with the Stealth TB.Fuel Injection Performance with a Carb Appearance.
