Mass-Flo injection
Has anyone here ever used a Mass-Flo injection system? Seems great - a little pricey, but apparently it's pretty headache-free and user friendly and infinitely tunable.
I've never seen or used one, but I've talked to three different people of late that have. So while I'm gathering data on this so I can make an informed decision on whether or not to buy, I'd thought I'd put the question to my Ford truck bretheren and see if anyone has experienced this. Thanks, fellers!

To Be honest the mass air seems good to me, i mostly drive early 70's windsors, it's that super quick throttle-response that i love. i thought about installing a mass air unit off a 5.0 Onto the early motor but was worried how it'd affect the feel. early windsors not only rev quick but idle down quick too. Except for late 80s dodges, most efi's i've driven have delay's in the response that i hate. my rare experience w/ford mass air is a 3.0 aerostar which wasn't ultra-quick but ok.

Not a good sampling of MAF EFI, I say.
I think this setup is pretty dang trick, I'll tell ya!

I just bought that system for my 302 and will probably get around to installing it early next year on my daily driver. Working long hours, holidays, honey do list, and other priorities have taken much of my time recently. Everyone I've spoken with who has it, had good things to say about it, as well as what I've read on other forums. All the electronics are basic mustang 5.0 stuff and it uses a corvette MAF. The small MAF the 5.0's used seemed like the biggest bottle neck. I found most of my info from forums and articles found by searching Mass-flo efi on google.com. Since my motor is'nt too far from the stock 5.0 spec's, (other than the 302 firing order) I don't think the "tune" will be too far off. He'll ask you about expected horsepower output so he can calibrate for correct injector size and firing order.

Thanks for the input. There are a lot of testamonials out there that swear by it. I actually spoke in person to one guy that was running this system on a low 10-second vehicle with 12:1 compression, high lift cam, a bunch of other gnarly go fast stuff and he said he gets 18 mpg on the highway because of the efficiency of this thing. Seemed a little hard to believe, but that's what he said. For me, those kind of first hand endorsements are pretty solid. I'm hoping to find a few more.

If you go with Mass-Flo, pay attention to the type of air cleaner you use. I was initially going to use a Ford racing or Edelbrock round chrome air cleaner. Since both of them were a drop base type, the base interfered with the IAC, fuel rails, and throttle linkage. I also found the air cleaner lid was way too close to the MAF and would definitly create air flow problems/restrictions. I ended up using a 14" Moroso chrome, flat base unit with a 3" filter that solved all of those problems.
I was seriously considering the Boss EFI single quad system by www.retrotekspeed.com before I got the Mass-flo. It's a TBI set up that bolts in place of a holly carb, that's also said to be "self tuning". That looks like a pretty simple and trick system also.
I chose Mass-flo over Retrotek because it's a port injected, mass air system which I understand is more efficient and forgiving, and it uses parts which can be found at any local auto parts store. At the time, the only testimonials I could find for the Retretek unit were the manufacturer and a distributor/installer.

Right now, I'm just putting the Mass-flo on my stock 302 79 F100. (2bbl, single exhaust, cast iron exhaust manifolds etc)
Hopefully next year I'll build a 5.0;
5.0 roller cam block
89-92 stock 5.0 Mustang cam or Ford Explorer 5.0 cam
9.0 to 9.5 comp ratio
Ported E7 heads ( www.thumperoforangepark.com )
Mass-Flo EFI
Ceramic coated stainless steel Ford Racing shorty headers
2 1/2 " custom fabed Y pipe
Flowmaster 70 series single muffler (quietest flowmaster)
3" single exhaust
Nothing fancy, just a nice little street motor.

..it's simply the truth. i know what i'm talking about i drove the 3.0 aerostar and dads 351w fairlane and my 66 f100 (the '68 fairlane's original 289 is unfortunately long gone, it now has a '73 351w same as my '66 f100) multiple times weekly. the old 2bbl windsors rev quick and let off quick and while the massair 3.0 wasn't bad for throttle response, but sure didn't hold a candle to the early windsors. don't get me wrong, i like the mass-air getup, i'd install it on an early windsor in a minute if i knew it wouldn't slow the response down, but i have a feeling that it would. if anyone's arguing with me here they simply havn't driven the old motors to know what i'm talking about-anyone who has must know i'm correct. i did drive a friend's '89 5.0 mustang a5sp a few times, it revved nice and quick for sure but it let off slow. i know whe difference i got out of the 5.0 right back in the old car and the t.r was simply nicer. period.

Your difference in throttle response was cubic inches, gearing, weight - who knows what, but it sure wasn't the MAF...
