Have any experience tuning with boost? Would be interested in a collab.

I run a phenolic spacer on my sniper 1 the scooped 4 hole kind . I run it to stop the sniper whistle sound . It loses power at higher elevations pretty bad and runs awful and pops . Do you think this spacer could be the problem ? If so could I dremel in a groove into the spacer to make it read both sides .

I think this is the perfect example of how people like to over think and invent issues they then pass around and parrot, instead of actually just doing it and seeing.

Who are the ones saying it won't work? And why?

Before I even watch this video I'm wondering why it WOULDNT work..?

Se puede prolongar el cable can esta en un barco el sniper

Can I convert a sniper dual quad efi system to a single quad using one of the dual quad units ?

I regret c notching my truck🤦🏻 its gonna make it a lil more complicated Great video! The semi level switch is a great idea ! And in definitely gonna incorporate that onto my truck hands free is nice !

I have a sniper bbd on a jeep Wrangler 1987 the TPS when the engine is off goes to 98 when I push the pedal to the floor, but while it's running it won't go above 35 no matter how far I push the pedal

I always look forward to another DSGD video. Keep em coming!

Did you ever make these plans available?

Bahahahaha Flip it and reverse it!!

Excited for this build! I'm interested to see just how far the Holley Sniper can be pushed

New sub

I have no binding at all with engine off. With engine running it will hang 5 to 8 percent. N

Useful. Great Sniper content.

Awesome video, very helpful.

Would it be advisable to add a fuse into the relay setup? Or, if I understand correctly, is the Sniper circuit already sufficiently protected by the 30A fuse between the battery and main relay, because the current flowing through the pink wire is only used a trigger for the main relay -- and thus never flowing directly to the Sniper. Thanks! Appreciate the great content.

Awesome! This trick worked for me on my 1971 buick gs455 with holley sniper. I noticed the tps what a 1-2% causing a iac hold state at idle

I had same problem when I bought a Holley Terminator (original) years ago. Tried twice to fix, Holley and Edelbrock were no help. it's been in a box since. (Hunting after the Holley warmed to closed loop, I have the Edelbrock Air Gap performer manifold on a Ford 351W.) I still haven't tried round 3 - replacing the carb w/ the Holley Terminator again. Recently I acquired another Air Gap to cut the plenum divider down 1/2" and try one final time. Should I file the cut-down plenum divider to a "V" to minimize the turbulence below the throttle body? I see ONE other video on you tube that suggests this.

I like it

my god finally someone found the correct fix, yes wrapping the torsion spring one more wind will work but not correctly the proper fix like you said, holly tech support said the same thing, to loosen butterfly screws and readjust, glad i saw this video because i was going to wrap the spring one more wind making too much spring pressure against the throttle.

As a machinist for distributors are the most miserable distributor of the changes distributive gear, it's like they put the gear on and then they handed a guy a drill hand drill and said here drove home and shove this pin in it, not like other distributors where they roll pin is properly machine into the shaft and gear precision Lee done!

Great background music.

Everything is easy when you know how I even had my teenager looking at it for me I’m like there has to to be a tab on it to release it Thanks for the video saved me heaps of frustration and possibly breaking it

Did you drill a new hole for the roll pin or drill out the old hole? If so, my question is there a reason you can't use the old hole for the new roll pin? It looked like you drilled a brand new hole in the distributor shaft.

Will the sniper #2 work on a Ford stock 4 barrel intake manifold

Can I load a Sniper 1 config file into a brand new Sniper 2 without doing anything else (besides getting past the wizard initially)? Or do I still need to do things like setting the IAC/idle?

Question...I have a tune I am going to convert. Does the Sniper 2 continue to learn and improve on this tune or not does it remain the same? Thanks!

Thank you sir!

What kind of semi truck leveling valve did u use

Good tip! Always learning something new about these. Thanks!

I'd be very interested in any more Holley Sniper and Sniper 2 videos!! .. The original Sniper is still for sale at many outlets (at least on line) IMO It's not THAT much cheaper than the Sniper 2 .. that makes me think some people like it better. I'd like to know if Holley is still MAKING IT?? ..... Or did they stockpile a bunch for customers who still want the original??? Or is it just old stock lag online resellers have laying around??

Simply using the recommended. Power Distribution Module would also solve this problem. Good video BTW!!

Never stop asking people to subscribe, it is your right. Just dont do it before the content begins...that is tacky and offensive !!

What I’ve heard was there were issues with fuel distribution when using a duel plane. Some cylinders ran dangerously lean under hard throttle. I’m pretty sure I heard the guys on Engine Masters make that comment when testing some intakes. It was not a test of the efi unit itself. Without a dyno and o2 sensor for every cylinder it would be difficult to know. Probably drag racers who were good at reading plugs could tell.

Thank you ,it is still nerve racking to me

My dad and i messed around with this on an Air Gap and a Victor Junior. Dual plane can work pretty well if you run a spacer or hollow out the divider, but you will get a reading on the MAP that jumps around a bit which did cause minor issues at part throttle. In theory you do lose some of the low RPM/load benefits of a dual plane because EFI doesn't need the air velocity to draw fuel out of a carb, which is helped by dividing the barrels. But EFI does keep the benefits of the longer runners.

Just got my sniper 2 haven't put it on yet i have a 91 302 ho mustang engine stripped off all emissions stuff I'm using a 2 inch spacer will this spacer be a problem this 2 inch spacer helps performance greatly

I wanted to see that leveling vale install forsure

Thanks so much!!

Thank you

Thats not how my Sniper Stealth works with progressive linkage. I've watched mine while idling and only the front two barrels are spraying. After 40% my rear injectors start spraying. Idk if Holley made any changes or what but mine works flawlessly despite having a cracked mounting tab next to the 3/8" PCV port

I'll stick with a decent carb, and enjoy the little quality drive time, I get to actually enjoy the drive. At least until Holley, or some new competitor comes up with something more robust, as to not suffer such basic drivability/reliability concerns, even when buy all of their ala cart solutions, and still need to go to TH-cam EFI University to have a decent chance to drive to a show or cruise night, and be embarrassed by coming home on a "hook".!

Let me start, by saying I love most of the OEM based, EFI systems the hobby has used over the past 30 years. That said, for all of the money, Holley has thrown at the Sniper series, and all of the acquisitions of all of smaller independent legacy brands as well, I find the current RFI issue to be unacceptable... Obviously, this controller design and packaging is not as robust as it should be... I appreciate the "craft" enthusiastic users and quasi tech support independent guys like you, who really provide value, to the poor guys, who spend good money, and so much of their precious little hobby time, trying to troubleshoot a system, that has gone thru at least three major changes (sniper, sniper II, Terminator x, or whatever), and still haven't addressed this inherently unstable base design RFI vulnerability, it's plain pathetic. One has got to 🤔 think, a larger, remote mounted ECM, with the equivalent protective electronic filtering circuitry and a decently effective "faraday" cage design similar to what the OEM's have used for eons now, is long overdue.. You read story after story, of how guys buy these things, have problems, get help, buy the next "Gen", only to suffer some other drivability/reliability issue..

I have the Holley Terminator Stealth system, not Terminator X. Can I upgrade the 80lb. injectors to a 100lb or 120 lb. injectors the same as the Terminator X?

I have never heard that it wouldnt work. I have heard that it makes a funny noise if you dont use a spacer... And also that it runs better if you put a spacer on it

Great job like it .

Thank you so much!
