550-870 Sniper Stealth 4150 Self-Tuning Fuel Inj.
WOW!!! Awesome product. Easy to install. Most difficult part is O2 sensor installation and locating the proper wires to splice into. Directions are easy to follow and the images definitely help. Engine fired up almost instantly. HIGHLY recommend this product.... Installed on a 64.5 Mustang 289. .040 over bore. roller lifters and rockers. Stock intake. Mild cam. Instant throttle response, no hesitation at all. steady idle, I think a bit on the pricey side but well worth the cost. I highly recommend the fuel module in-tank version. no return line required. Follow the included instructions, read them, then read again, and again. there is a lot of helpful information included. I repeat TAKE THE TIME TO READ THEM!!!! they are most helpful.
