Graniteli Mass Airflow Sensor/ Supercharger

Hey yall I have had a question maybe yall can help me answer. I bought a Graniteli Mass Airflow Sensor and use to run before I put on my Procharger. But after I installed the Procharger man I had tuning the truck told me they were junk and my truck would probably run better with the stocker. So I took my stocker and took the screen out of it and got it tuned by another man and just left it off. That thing is alot of money to have just sitting around not being used if I put it back on do yall think it would help performance, effect my tune, or do I just need to keep my stocker without the screen, and sell my Graniteli. I thought it would help some, just like to hear some other opinions. :duh:

Put it up on eBay or list it in the classifieds somewhere. The stock MAF on your '02 has way more air flow measuring capacity than your current hp/tq ratings.

On the stock MAF screen removal, one thing that screen does is help atomize the air so the sensor can get a better reading. Delphi put it there for a reason. I have never seen any reputable data that shows this "free" mod accomplishes anything , except maybe cause problems :twocents:

:imwstupid:

my descreened maf caused a little problem. nothing major but allen was fighting the maf to get a good tune into my truck. ive since found a new factory screened MAF.

Yeah Allen had problems with mine too, it was pinging was more than normal. I switched to a screened one and boom! Best tune I had until i switched to the 02 PCM.

when i took out my stock MAS an put in the granatelli it was a big difference for me

the granatelli will work for some people and there mods. every truck is different. for the most part it makes people run lean. if you are going to be forced induction do not put it on. remember it is designed to help out trucks that are very lightly modded. put in the mas air with the screen in it and you will be better off.

oh no u went to the dark side lol

yay i figured it was the only way you people were going to keep up. :taunt:

actually it was a family decision. but not all is lost. i will be helping a friend build a camaro to toy with.

OOO.. I appreciate all of the replies so yall are telling me I would be better off to put a stocker back on with the screen, I thought would badly restrict my truck especially with it having a supercharger. I do get yalls point were yall say it can get a whole lot better reading for AIR/FUEL. Will any of the MAF Sensors work on my 02, or do I need one that has came off of a 02. Pretty easy for me to fine stock parts we own a big towing business. Thank yall for all of the replies. :burnout:

find one with the same code on the side. i think their the same from 99-now on 4.3,4.8,5.3, and 6.0 and maybe even teh 8 liters

well did you go back with the stocker???

I only ran the GMS for lil while, and I have been running my stocker since. My truck is running fine so I guess I'm not going to mess with it, I guess I'm just going to try to sell it. My stocker does not have the screen in it, I heard the the ones with the screen actually perform better, fine that hard to be especially mine being forced inducted. But I do understand were they are coming from because it would be able to get a better reading. But ooooo welllll haha i'm run my STOCKER. That GMS can fine a new home. :burnout:

hell stick it in the classifieds all over...someone will want it...
