As a gen1 owner, sure seems like a lot of "things we probably should have done the first time"

[BiggestLittleTrucks]

This video is great for when I do my Holley Sniper 2 install on Ford 429 big block. Can't wait to see how it performs!

[novaguy]

Watching these videos really makes me want to get going on my current project or to start the foxbody build id like to do...

[ricardomoreira]

I had just bought my sniper 1st generation .... few days later, you guys started to sell the new generation, almost with same price.

[PopoMedic]

Just picked up a rig with a sniper but the display is disabled. Can’t adjust the settings. If y’all can help lemme know.

[johnm]

Based on all the concerns gen 1 owners express and the lack of support to upgrade them to gen 2 the jury is out to purchase this system. It’s a shame Holley does not step up to support customers who support them.

[HotRodGuyGarage]

Is the ECU still potted in a jb weld type substance? Are the throttle shafts bushed and sealed now?

[frangerxlt]

Does it have ability to supply oil pressure to the 5" dash, with the additon of the transducer of course?

I have a 347 Stroker motor with a Weiand 174 Super Charger. I'm excited about the Sniper 2.

I have 3 questions:

1. The fuel system option offers a Universal Returnless Drop in Module, so would an EFI Fuel Tank Module PN's 12-305 or 12-375 work with 5/16 inlet (The MUSCLE CAR EFI MODULES;) then would you duel feed the Sniper or cap off one of fuel connections?

2. Page 18 and 19 of the Quick Start Guide show the wiring harness (PN 558-191, and 558-190)(non PDM harness, and PDM harness) using 14ga wire to power the fuel pump; What amperage is the circuit limited to?

3.What would be the wiring diagram for a Pertronix distributor on the PDM, and non PDM harness with a CD box?

I'm just doing homework research to know what issues I'd be up against. Have a Hot Rod day 😊

🏆 i need on for a 350 Oldsmobile motor 1972 cutlass. Keep up the great work and this video

[stevekerr]

Hi, just installing a sniper 2, can I plumb the pcv valve into the front of the sniper 2 where the bung is, and also would it be better to run the ignition feed directly from the battery via a relay from the ignition to ensure a good 12volt supply

[Randomgearhead]

Hope u provide Delphi sensors that read accurately

[CC-zgvt]

Hi! Will there be a controller for the 545rfe transmission coming soon with the sniper or terminator x ?

[caboose]

Y'all should definitely do a quick vid on how to replace/integrate factory computer controlled/fuel injection with this kind of system.

[carlj.]

I have a 1952 ford with no return spot on my fuel tank. Do you have to have a return line on the Sniper 2?

[brundon]

How does this differ from the Atomic 2 EFI system from 2021?

[date]

Is there going to be a sniper 2 2300 2brl

[maxwelltatro]

Does this system work in marine applications like the sniper 1?

[andysteward]

I’ll come right out and say it, the Holley ProJection was just plain better. It had better instructions, and the controls were analogue. It just worked.

[sharpcf]

Can you run two together, with a 6/71 blower. Zoomie exhaust, so none of them come together, could only pick up one on the o2 sensor. Lastly would it work with the Holley efi standalone?
