Has anyone used this system or heard a lot of pros/cons about it. My friend wants to order it for his big block coronet and I didn't know if it was worth all the money.

I am always skeptical of EFI system that claim to tune themselves without the need for you to tune it with a laptop. I sure do hope their system at least gives you the ability to tune manually with a laptop in case the system is unable to properly tune itself in a given instance. It could be a good system, and sure does have a nice looking throttle body/fake carb there. Also, the system is still going to be a TBI injection system. You still have to deal with the deficiencies of a carb intake. IE fuel/air distribution, still need good vacuum for a very streetable setup, etc. With say port EFI, you can throw all those old carb rules out the door like engine vacuum, intake design, etc. But with a system like this, those same rules would still apply. I'm sure their system would still be a little better than a carb, but IMO you'd probably be just as well off if you bought a nice holley carb and a wideband o2 and spent some time tuning the carb on the primaries, secondaries and tweaking the choke. But I have no actual experience with their kit, but it just seems to me like they're just trying to sell you efi with the idea that it is strictly a bolt-on and go like a carb.

I wonder how this set-up would work with a turbo or blow thru supercharger? FAQ on web site only talks about Roots/GMC type.

Sure they will.
But seriously, I have done some research online a few months ago, and all I've read are bad things.
Of course, I take everything on the web with a grain of salt, but it seemed theye were a few frustrated users that couldn't get customer service, IIRC. But, hey, don't blame me for starting rumors, do some research at hotrodders.com, I think that's where I found some info.

I had a customer that took his off and bought a FAST system. He said he wanted better tunabilty. He wouldn't tell me much more other than the system was not totally self tuning - he still had to start with a program that was close for his combo. He already had a buyer for his RetroTek so it was a moot point.

I would like to hear from Randy about his experience.

Wow! That was fast. Randy just called me. How's that for a quick response?

He said it would probably be a fine system for a pure stock engine. But they had a few issues because his camshaft was more performance oriented and had a tight lobe separation. So he never could get it to run any better than a carb. He also said that they offer a system that did not use a fuel return line and that he would not recommend that. Always use a fuel return to the tank with EFI!

An electrical glitch killed the box so he took the system off and went back to a carb.

He mentioned he could download various programs, which he did several times, and the tech support was good.

that's info that needs to be published in follow ups in the magazine...

did he elaborate on the glitch that killed the box? was it a problem with the retrotek system or improper installation (i.e. a short, etc) that killed it?

He didn't know what happened, but it wasn't related to the installation. It was internal. He just sent it back and they took care of it. He said he may do an update post on the MM web site but it's unlikely he'd do a complete follow up article.

And that's why we read the internet (and in my case stay away from MM)...Thanks Rich.

Why do you need good vacuum for street with a TBI and not a SMPI? Does the fact that the injector is squirting fuel at the back of a closed intake valve over 50% of the time at WOT with a SMPI negate the advantages of even air/fuel distribution. I'm thinking of going with a Holley 4bbl TBI and a Megasquirt system. I can't put fuel rails on an old car. It just looks like [Edited by Moparts - Keep it clean] to me.

I don't know quick your car will be with this system, but the price will sure empty your wallet fast.

If your gonna sell something that's marginally better than a carb, at least price it somewhere in the neighborhood. For 1500 they wouldn't be able to keep them on the shelf.

The point is when you hit the throttle, a map sensor for either tbi or mpi will instantly detect a vacuum change, but with a tbi, the engine still has to suck the fuel from the throttle body, down the runners to the valve. With port efi the fuel is right there. There is no delay in transit time. TBI will still be more responsive than a carb, but still not as good as port injection. It's a good middle ground, especially if you don't like the look of fuel rails.

750 cfm in machined finish for $2500... That's enough to get a real injection system... or a new Hemi take-out engine...

Despite the price I can see where the allure is to one of those kits. They say you don't have to do any manual tuning, which on an efi kit is what scares most guys. IMO these kits could work well on stockish engines that still pull a lot of vacuum. But throw in a big cam, high-flow heads and intake and who knows...?
