Using a 4150-style flange and a recessed base, it drops right onto single or dual-plane manifolds. With support for up to 650 HP naturally aspirated and 575 HP under boost, the Killshot 2 Pro is made to feed whatever you're building: street bruiser, boosted weekend warrior, or nitrous-hungry drag car.\u003c\/p\u003e\n\u003cp\u003eAn integrated 3-bar TMAP sensor supports up to 27 psi of boost for turbo and supercharged applications, while four 100 lb\/hr injectors comfortably feed up to 650 HP per throttle body. Need more? Run dual-quad and fuel up to 1,200 HP (requires an additional secondary throttle body unit and larger pump; both sold separately).\u003c\/p\u003e\n\u003cp\u003eIt's already compatible with blow-through, draw-through, and nitrous setups right out of the box. And when our boost control software update lands in Fall 2025, the hardware inside is already ready to run with PWM boost solenoid control for true precision under pressure.\u003c\/p\u003e\n\u003ch3\u003ePower Meets Simplicity\u003c\/h3\u003e\n\u003cp\u003eAt Aces, we build EFI systems that make serious power simple.\u003c\/p\u003e\n\u003cp\u003eThe Killshot 2 Pro is a DIY-friendly system designed for enthusiasts of all skill levels. Wire it in, answer a few setup questions, fire it up, and the self-learning ECU takes over by fine-tuning your fuel maps automatically. For most street builds, that's all it takes. For the tuners who want total control, our free laptop software unlocks full manual tuning access, which is ideal for mild to aggressive builds running high-lift cams, forced induction, or nitrous.\u003c\/p\u003e\n\u003cp\u003eOnce your engine reaches operating temperature, the system goes closed-loop and starts learning in real time. After a few drives, your tune dials itself in, and when you're happy with it, you can disable learning and lock it down. That's confidence you can feel at every throttle blip.\u003c\/p\u003e\n\u003ch3\u003eIgnition Compatibility\u003c\/h3\u003e\n\u003cp\u003eWhether you're running an HEI, canister coil, or aftermarket system like MSD or Holley, the Killshot 2 Pro plays nice. It can also digitally control timing with a Hall-effect or mechanically locked magnetic distributor and works seamlessly with CD ignition boxes.\u003c\/p\u003e\n\u003cp\u003eIf you're looking to go all-in, Aces offers complete Hall-effect and magnetic distributors, ignition coils, and fuel systems designed to work together for maximum reliability and spark control.\u003c\/p\u003e\n\u003ch3\u003eChoose Your Setup\u003c\/h3\u003e\n\u003cp\u003eWe know every build is different, so we made the Killshot 2 Pro modular.
