Has anyone tried this item from Granatelli???

Has anyone tried this new Mass Air Sensor from Granatelli??
Link - http://www.granatellimotorsports.com/pr046.htm
Just looking to see if it worked and what people (If anyone has tried it) thought about it
Looks interesting has a fuel ajustment deal and flows 30% more (Per them)

On the web site the LS1 Mass has gotten so really good reveiws, so I was thinking of trying one but am leary since a buddy had problems with one on a Mustang years ago
anyway post your coments and or feedback
Thanks

Their exact words are: "The Granatelli Motorsports unit flows up to 30% higher airflow rate than the original".

They're very shrewd in how they worded that claim to make it appear at a glance to say what you've quoted, which isn't what they said. They are specific in saying *rate*, instead of just saying 30% greater airflow. I'd be concerned about what the truth is.

Buyer beware....

I dont doubt that it would flow 30% more airflow. Just look at the design. problem is, that its a one size fits all calibration, and the signal it sends to the computer may not be the signal it wants to see. Usually the only way to run an aftermarket MAF and have it work right, is to have the ability to adjust the fuel and timing curve through other means. This is the purpose of the translator we use with LS1 MAF's. It gives a good baseline voltage curve that we can tune around. The adjustment screw on that thing isnt going to fix the whole curve. You need to be able to control the idle/low flow signal and high flow signal separately. Pro-M has units that offer this. If you're set on an aftermarket maf, get a Pro-M. Theyre probably the best in the business. Ive used their stuff before and it works really well. Every MAF comes with a calibration sheet thats packed with data.
Holy crap! they want $475 for that?

FWIW & IMHO:
Buy that and you will be the laughing stock of the turbo Buick community.
Do a search on this and the other turbo Buick boards.
Just send me the $ 475, and I will pray for your car, and it will run better.
Really.

They have a PN for 86-87 GN And T-Type all alone Found it on another site linked to theres in the dealer section

You run a Pro-M on your Buick?? I didn't think so....

IMO:
Don't know how well it works but I bet a stock replacement from Auto Zone Advance, Pep Boys...will work too.

At that price I would have a hard time not going with MAF Trans+ from Full Throttle Speed. It usees a known good MAF system that is readily replaceable and has some serious adjustability.

It was an "if all else fails and you insist on an aftermarket MAF" scenario. Honestly, I dont know if Pro-M even makes MAFs for buicks.

 

[87GN_ponykillr]

I have one and I like it, It does flow much more air and you can see the diffrences. It is not cheap tho.

One, what?. Pro-M, or Granatelli.

You purchased the Granatelli meter and you like it??
I see its 400$ but I also dont like the T+ and LS1 Maf set up. Have 2 friends with them and throttle responce is lower the cars never seem to run the same. (Sorry Mike just how I feel) You can play with them till your blue in the face and not get the same responce as the factory set up.
The cars due go faster due to more flow I will give them that But for the street I can whup both my budys that have T+ set ups right out of the hole and we are all using the same bolt on parts other than the LS1 LT1 T+ set up. They get me at the top of 2nd gear when air flow is more though

Besides this cost about the same and I just want to see what others think of it.
You can also find them on JC Whitleys site for $399 and list the same P/N on there for the 86-87 GN and T-Types as in there site, and that my friends is cheaper than a T+ and LS1 LT1 Maf

I like that!

Junkyard Ls1 MAF- $75
Used translator off ebay or the TR boards -$100
Spending $475 for a factory replacement MAF- Stupid

 

[Gary Wells]

FWIW & IMHO:
There is a lot of info on this product on the boards. Really should do a search on tbs.com, t6p.com, Ihadav8, & this board and you will find enough info to help in the decision. All of the corvette forums have a lot on this subject also.
Such as this one here:

HTH

You are not running a Paxton blower or using STP in your car, are you?
FWIW: In their racing days they were referred to as "the Katzanjammer kids"
from the old comic strip of the same name. Do not ask me how I know.
Go figure, huh?

Have you tried Direct Scanning all 3 cars to see what the differences are?. With that info. you might be able to get the same responsiveness.
BTW, what chips are you running with the T+?.

I'd have to agree. Seemingly identical cars usually have some pretty important differences that get overlooked.
Besides that, if you read his post carefully, he finally admits that he still gets his butt handed to hiim by them, races are never decided in the first gear or two. It's what happens down at the "other end" that counts.

Yes they due beat me but not till the top pf secomd gear!!!!! THAT IS NUTS!!
And also there around town drivablity is sh*t and I mean very bad, as in sluggish. One car has the Mike Litch Extender chip, the other has a chip from Eric at turbotweak. I run a chip from eric and I love it! best ever. The chip eric did for my budys car is almost the same as mine (again all 3 cars have the same Fuel Press. Reg., Same Turbo, Same Plugs and wires, Same stock IC, Same Stock TB, Same Inj. Everything, The only reason they get me in the upper end is air flow, In the freeway guys I still can get up to speed faster from a roll due to the better throttle responce I am getting.

I personally think there are to many ajustments that can be made on a T+ and this makes tunning a real chore

Both cars run good, just slow Throttle responce, and I have also been told this by a bunch of other guys that they feel the stock Maf has better "FEEL" and Responce around town and out of the hole. I personally do not want to lose this since I run my car 98% on the street and in trafic.

Anyway Ill will look over the rest of the board for more info on this one

Wow, I find that one tough to swallow. The MAFT+/LS-1 combo is better in every respect than either of my TR's was with stock MAFs. Add to that, new LS-1 MAFs will be available indefinitely.

[thunderace31]

Well All I can say is this is what we are finding and we are not the only ones with this opinion many others out there are telling me the same thing. Also I have heard it from people how work at or have worked at Agressive Automotive, Livenois Motorsports, Ramchargers (Not mike litch of course lol) and a few others.
I am not saying they are bad and may be loads better once you get them tuned in but damn we have been playing with these for 5 months and still the same B.S. I am looking at maybe trying the Mafless deal mike has coming out soon. just to see if it is better.
I dont like the the T+ set up at all, and I also know I am not alone

 

[ross87t]

$475???

Uhmm...Translator+, LS1 maf, and an Extender Extreme chip would be a MUCH better combo at that price.
