My FI Tech Go 4 system was shipped the day after ordering. Same benefits as the MSD atomic, controls ignition and other accessories plus infinitely programmable and no external control box...all internal. I opted for their Command Center combined fuel sump and pump which simplifies the installation a lot...all for about half the price of the Atomic.

Monte,

Are there major benefits to go with a direct port over a throttle body type unit? I just bought an Indy 400 intake that I need to get drilled for injectors. If the benefits are huge, I may just hold out for a new throttle body kit

Direct port injection is always more efficient and easier to tune.

In regards to the FiTech unit:

-What pressure is their integrated regulator operating at? And is that pressure fixed?
- Can it do PWM or control pump speed? I don't think I've read much, if anything about that.
-Last question and I know this is subjective but, are you satisfied with the fit and finish/quality of the product? Not in light of it costing half as much, but as an aftermarket item you're putting on top of your engine.

I'm in the throws of building a budget SBF (gasp!) so this is an appealing option.

This is how I set up my Holley multi port.. I like
the looks and it hides well under the air cleaner..
I was gonna cut the injector bases down .040 but the
injectors clear the base by .060(if they touch the
base they will make noise when they open and close)
EDIT
I would have turned the one set of injectors around
to the inside but my kick down set up is there

Fuel pressure from the Command Center is fixed 58 psi, don't know about PWM capability of a different pump setup.

The quality, finish and attention to detail of their products is superb.

Thanks for the feedback, John, I might PM you with some other questions.

I Talked to FI Tech, they were very helpful. They have the units but the pumps are back-ordered but they said I could use a standard Walbro 255 for the 600HP kit if need be.

Was trying to find a deal on the Atomic s

FITECH looks like a very nice product. i like how the injectors are arranged at an angle around the circumference of the venturi to cause a swirling flow pattern. Engine Power did an ad for them at the end of their show sunday. price is nice as well.

Installed on 55 T Bird Y block to replace stock Holley 4 barrel T Pot carb. Had a really tough year troubleshooting an engine stalling at random times when coming to a stop. Very dangerous on Calyforuna freeways.

One year of dealing with MSD tech being told that I was doing something wrong or it was the engine. Much time spent on their forum where technical problems were endemic. All the time me telling them to fix their software.

After 3 software update/refreshes all now appears well for the most part.

Will now report that starting, idling, fuel economy are much improved compared to the miserable old Holley.

A very strong point on the MSD Atomic,,,no one knows it is there when the hood is up. I've numerous updates to the car,,,AOD 4 speed overdrive automatic,,, Borgeson steering Box,,,etc , and yet car appears stock except for the Vintage AC add on.

Beautiful T bird buddy, very cool install!!

I was really interested in the FiTech unit for an upcoming build. I called them on Monday and talked to a couple people there about the product. I then decided to pull the trigger and ordered a GO EFI 4 600hp unit and it arrived at my door the next day. Very pleasant people to deal with and from everything I've seen in the kit, the fit and finish is easily on-par with the MSD and Holley units. I am not found of their clamp-on style of 02 sensor bung and would really have preferred ORB style fittings at the throttle body, but those are my only two gripes. FiTech also make provisions to tune via a laptop if you desire.

If anyone curious about the system is interested, I can also take some detailed images of the packaging and components.

I would LOVE to see some detailed photos of the actual product.

Me too! Thanks!

As requested, here's a gallery with closeups of the FiTech system.

Will a drop-base air cleaner fit over that throttle body?

I wondered the same thing, it looks like it would though. You might have to run some 90* fittings off the fuel fittings but looks OK. I would hope that they thought of that.

Yep, that's what I'm running on mine.

From one of the manuals:

FUEL PUMP CONTROL: The FiTech ECU for Go EFI systems has a special driver circuit that will drive the fuel pump directly, which means that an external relay is not needed. This driver circuit allows both PWM control (pulse width modulated), and direct internal relay drive of the fuel pump. This allows the voltage to be reduced when the fuel demand is low, such as at idle and light cruise.

One thing I am not a fan of is the seemingly limited tunability. Looks like a 3x3 spark table is all you have...and it seems they strongly discourage people to actually fiddle/tune.

Thank you for your kind words. My wife's car, she appreciated the compliment. Here's a shot of the car.

Well please tell your lovely wife that this die-hard MoPar guy now has the picture of her most beautiful T-Bird as his computer wallpaper!! What an amazing looking car.
