Yes sir. Only issue I've had is I had to readjust the butterflies as they were sticking when cold. I'm guessing the new "better throttle response linkage" was to fix this common problem. The CANbus connectors are a bit of a pain but I wish they would've stuck with it. I have it all set up with a Y-splitter to a laptop USB connector in my console. Sucks i'd have to change it all if I ever upgraded. I guess I could go the bluetooth module route and just use my phone instead of the 3.5" display and then bluetooth to my laptop as well.
My thoughts exactly, I wonder if they are going to offer a trade in trade up for the new unit. Especially since I had to send mine back twice for loose injector connections. Oh and I also purchased the $ throttle adapter.
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.
Almost nothing is these days. When a new phone or car comes out you don't get an upgrade because you supported a company, you're stuck with the old model. It's just capitalism.
Just installed a sniper2 with the master fuel kit, very disappointed with the cast fuel pressure regulator. Both the one that came with the kit and warranty replacement leaked and sprayed fuel all over the engine. I ended replacing with an aeromotive one to fix the issue.
I want to see the Xflow 1375 capabilities with Sniper 2 and e85 compatibility. This way on can take a non-LS and go four figure hp with boost and a simple system. For example...a 351w(or stroker) with aluminum heads and single plane, a Vortec 5700 or 7400, Ford 429/460, PSI 8.8/ Vortec 8.1, Mopar LA/Magnum, B or RB, Ford 240/300, Mopar Slant/Hemi six, AMC 4.0, 232/258, Gen 1/2/3 Hemi, Buick 300/340/350/400/430/455, Rover 215/4.0,4.2,4.6, Olds 350/400/425/455, Cad 429/477/500, AMC 304/360/390/401, Godzilla 6.8/7.3
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.

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?

Years of development that has included nearly 5000 hours of test stand run time, extensive thermal testing that included temperature sweeps between -40C and 200C, and thousands of real-world miles on a variety of engine platforms
Thank you for going into more detail on the tuning process. This is helpful for Gen 1 as well. Any plans on an upgrade program? Trade in your gen 1 for half off of gen 2? Also will the new bluetooth adapter work with the gen1 with a harness adapter?
Great video. Stock 289 65 Mustang a friend wants to run this on, mechanical secondaries with an auto and 800 cfm sounds like a bad combination. Is this a problem that will create a bog from a stop? Stock gears. Any input appreciated. What's the best CFM for this little engine with this combination?
The cfm with fuel injection is not a problem with fuel injection because its forcibly injecting the fuel where carburetor it does matter because you need a metering signal ie air speed for the carburetor to work properly
@@cmkmd Thanks for the input. I see what you mean on the fuel side but would think velocity would drop to little or nothing creating the bog. 600 to 650 would be more than enough for this engine I would've thought.
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
@@HolleyPerformance thanks for replying. I’m assuming the original Sniper does not support E85 then either. Is it due to the injectors and seals not being ethanol compatible, or is it not rated to flow enough ethanol to hit the HP rating?
Depends on which fuel cell pump module you select. We offer return and returnless versions. If you purchase a returnless module, a regulator is not required.
Going by the video you can run the msd distributor but it will not control timing which is a blow to me as I run the full msd including the 6 AL box to control timing on my sniper 1 . @@Kylersbuilds

I just received my Sniper 2 upgrade kit (after investing almost $3000 Canadian on a total failure and struggle with a Sniper for the past two years (in for a penny, in for a pound) and the thing arrived (direct from Holley) with no fittings for the fuel pressure regulator and now I see in this video that it needs a pressure gauge on the regulator?

@@MikeBaxterABC I was told by a Holley Tech that one of the first things you should check when looking into running issues is fuel pressure so I need to know what it is at all times.
You should send 1 of them to replace the gen 1 garbage I bought that never worked and yall refused to fix. That would be a good business move !!!!!! 1💁
Sold mine after years of frustration! and was told I needed to add a lot of extra grounds and shielding for the wires. Mine was in a 4 speed and was told not to engine brake as it confuses the computer and would either die when you push in the clutch or lose iac counts and take off.
Yes, Gen 1 had issues, just like Terminator X. We had our tuner turn everything off once we got it to where it needed to be. We blew out 3 O2 sensors because of over fueling. I think this version should work very well, but long overdue.
Holley should really offer an exchange program for all of us that spent good money on the original, junk Sniper 1 if they hope to have future repeat customers. This thing is a complete piece of garbage. How about like a 75% off coupon and we can mail you back the old piece of trash Sniper we got screwed on.
As a gen1 owner, sure seems like a lot of "things we probably should have done the first time"
Agreed

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