Attention EFI Users

I’m getting ready to pop the fuse in ordering an EFI setup. I’ve watched numerous Utube vids on Fitec, Holley Sniper and the Edelbrock system. My biggest concern is customer service. Any comments concerning the customer service for each?

I have a 74 D100 with a 318 auto which is my mule for setting up a system.

I've installed a FiTech in my in-law's Truck. It runs quite well but the interface is pretty clunky.

When it's time to put one in my Warlock, I'll give Holley a try. A huge amount of the installation troubles are user induced, primarily around RFI/noise and adjustments that need to be made by the user.

I'm running the Holley HP unit... holley has both a call service and a very good on line service

If you are worried about customer service, go with the Holley. They have had the best I've dealt with on all different units. FiTech has been iffy at times.

I'd recommend buying a factory refurbished Sniper for $800. Add the Hyperspark distributor so you can control timing and you'll be all set. You'll also need a high pressure pump. In tank is preferred but that might not be an option on a pickup truck.

That is true. I visit the Holley Sniper forum on a regular basis and many if not most of the problems that people have are because they didn't read the instructions. People bolt them on and start playing with them and then it doesn't run. Installing EFI isn't the same as bolting on a carb. It is more like getting a new laptop to work. Things need to be connected properly and the files have to be loaded into the right spot and the cables have to be routed correctly. It isn't difficult to do, it just has to be done correctly.

If I were to buy one of the Throttle Body units on the Market today It would no doubt be the Holley.

Another vote for Holley. I have a Holley Dominator EFI on our Hellcat swapped 71 Barracuda, and just installed a Holley Sniper and Hyperspark distributor on a friends 66 Mustang. Customer service and tech were fantastic.

A little off the intended subject I was looking at the intank fuel pump and it seems that the inline pump would be the way to go. The only complaint I’ve heard on the inline is the noise. I have a Tanks Inc. 16 gallon located behind the rear end and can always switch later if the inline doesn’t work.

Installing a Holley Sniper right now. All seems to be pretty good but I was a tad bit surprised to find out the CPU learning curve is about 500 miles. On the other hand, maybe not.

We've done both Sniper and Fi Tech. They both worked well and had little to no issue with either

Thinking about it, I wouldn't be surprised if Holley winds up owning FI Tech, That seems to be a common tactic when they have strong competition

Do NOT route any of the wiring close to any plug wires or the alternator.

A friend of mine learned this the hard way on a Sniper install. He's pretty OCD about making things look like factory and he had to tear it all out to reroute everything. Tough way to learn all about EMI and RFI lol.

He said there was no mention in the installation manual about it either tho they may have updated that if they've had enough complaints.

Hasn't arrived yet and I still to finish the engine build, but my son came over last night and ordered the Holley Sniper and distributor for his 440. Still have more stuff to get, but this time around the 440 will have more cam along with fuel injection. Hydraulic clutch setup, too. Still considering power steering so that it will be easier for his wife to drive it plus we don't have any real good manual boxes...

I sell and support Holley EFI. I DO answer the phone too!

how does the sniper system act with 260/270 duration @ 50 cams ?

FiTech's Customer Service SUCKS!

What about mounting the Sniper to a Performer. I also saw a vid where a duel plane screws with the MAP sensor. Have to add a spacer or cut down the intakes divider. Is this true?

do you still support FAST also, the biggest piece of crap ever produced, that I spend thousands ,because you also supported, all I ever heard from them was your out of warranty,as my quad driver failed twice,and flooded the motor .... met with u at Carlilse years ago and you had no answers,and I was not the the only one, every one was having problems, you just blew it off.....PATHETIC....

The Sniper must be manually tuned to handle low vacuum cams, but I do it all the time. Most people don't even know that the Sniper can be tuned with a laptop because they bought the Sniper in order TO NOT use a laptop, but it does have that capability. It has saved many people from having to go out and buy a higher end product.

FAST was one of the leaders 10-15 years ago and their higher end XFI products still work, and yes I am one of the ONLY people that still answer the phone and I will support a FAST user if they have one of the higher end products. FAST made a mistake with the lower end systems. There's nothing I can do for an EZ user where I cannot get into the software. 99.9% of my sales are other products, such as Holley, but I still want to help if I can. So I actually DO answer the phone and I'm proud to be known for that.

Yes - sort of. Dual plane manifolds were made to generate a signal that a carb needs, but TBI EFI systems don't need that. And EFI needs a map signal that represents the entire map that the engine sees, which is more consistent when using an open plenum. An open spacer or a cut down divider is a way to do that when you start with a dual plane manifold.

thanks for answering my question Rich !
the fuel system i'm putting in my charger is being designed for FI down the road, although when i get it running again, it will be carbed.
i now have a 3/8" feed, and i'm going to bend up a 1/2" return.
i just purchased an aeromotive 340LPH pump, so the next move is a regulator, hopefully one that has high and low pressure capabilities so i don't have to buy it again.

So, is there a standard rule for the amount of space the throttle body needs?

Sounds fair to me.

That's a tuffy. Any amount of opening helps, but there is no magic number because camshaft parameters affect it. There are thousands of Sniper users out there that never did anything about their dual plane manifold and they are running fine. Sorry to be vague but it's the truth. Use a single plane if possible is all I can suggest.

I have a thick spacer/gasket on the Manifold now. Might just work. The motor is a stock low compression 318 with a Performer manifold, headers, an electronic distributor with a fairly lazy advance curve and a MSD 6A.

Holley also has a EFI forum that is broken down by specific model lines like Sniper, HP or Dominator. There are also numerous Holley EFI Facebook pages that get tons of traffic with technical advice and questions.

Most of the race tracks I go to I see the majority of the cars running EFI conversions are all Holley. So you are more likely to run into other people that are familiar with Holley than the others in my experience.

The question is sort of irrelevant to the EFI used. I am running a Microsquirt system with dual 1bbl TB's on a reproduction dual 1bbl intake for my flathead six. I had to make a 1" adapter to mount the throttle bodies to the intake and I tapped both adapters to feed a common source to the MAP sensor. With the 4bbl TBI setup you still need a common vacuum source but it doesn't have to be anything huge, just enough to tie both sides together. A thick gasket may do the trick. Pic shows my setup to feed the MAP, if you had stack EFI you'd still need to tie all eight setups together to provide a common source.

that is a REALLY NEAT setup you have there for your flat six !
i'm pretty sure you have said before, but is that a 216 ?
are you running an overdrive on your three speed ?

Pretty trick

Original 218 and no OD on the trans either

This will get interesting on my son's 440 then. Stock 1967 intake (four hole). There is no room for an aftermarket intake unless there is one that is exactly the same height. It would be easier to modify a 1970 factory intake due to it having two oval holes (sold the one that I had). Would you mount it (Holley) and see how it goes or...?

Yep. Many people do that and are okay. Too bad you don't have enough space for a 1" spacer.

When you run this air cleaner and plan on using the air box as well things are real tight AND the neck is already cut down on the base...

Do what was suggested above. Pop a small hole in each side of the manifold below the carb pad and link them together with tube. Tie that to the map sensor. This assumes you have a separate map instead of an integrated unit.

That is a HUGE bonus. My first EFI system was a rather obscure unit that works opposite of most. I struggled with it due to nobody knowing how to tune it and the learning curve was steep.

I believe the Map Sensor in internal to the throttle body

In that case you'll likely need to remove a fair portion of the divider between the two sides of the carb pad
