Jet performance MAF sensor

[flyingfool]

so i stumbled across this video on some dude saying how great this MAF is, but why is is different from OEM? 

are we exceeding our MAF sensor limitations in the stock setup?   

 

Any ideas how the JEt MAF out performs the oem  function in the ECU... please enlighten me..

I am sure it is as good as the other jet products, like thermostat. Haha[emoji38]

I bought a Granatelli Motorsports MAF for my 99 SCSB.

 

Basically what they did is remove the dust screen/filter. If you look inside of your MAF, you will see a set of "sensors" and a screen that looks like a "screen door". What they did is remove the screen so the air flow is "increased" into the throttle body. At that time there was also a product from Tornado Industries, that would create a swirling effect of the air going into the TB.

Kind of a cheap/poor mans version of a Supercharger, mostly just sounded cool under WOT, with the whistling effect it caused.

that's what i was thinking , intermittant sometimes it works sometimes not so much.. lol probably another salesman selling junk to the masses

interesting , I will examine my oem unit a bit closer.  thanks Jim

You are very welcome.

 

Now you have me thinking, what else do I have in my tool box. There was another company in that era that had a TB space, looked cool, just made the hard acceleration whistle louder, maybe I should start listing some of this stuff on here to sale. 

One difference back then was, it was still a throttle cable, not DBW like now, so you did have a little more input in what was happening during acceleration.

The first old school maf had screens and everyone would remove them. It was bad then people bought plastic no center bar maf ends. Worse idea. All snake oil and that is if it even ran right.
The new version are different and are not a limit at all.
Here is a stock gm back up I have. God I have to much junk.

Guys, I read the page description and seems like not even Custom HP Tunes can compete with this single $250 dollar sensor. The scary part is all the "people" in the comments who say it works

 

The JET Powr-Flo Mass Air Sensor delivers improved horsepower, torque and mileage from your car, truck or SUV by simply replacing the restrictive stock mass air sensor. The factory sensor not only is a major restrictive point in stock intake systems, but it also limits the full potential of aftermarket cold air intake systems. The flow bench tested design of the JET Mass Air Sensor provides airflow increases of up to 45% and installs in 10 minutes or less. Compatible with other aftermarket upgrades such as computer upgrades, cold air intakes, TBI spacers, free flow exhaust systems, etc

In all seriousness now, OP, for more throttle response, add a wooden stick behind the throttle pedal assembly, that will give a noticeable change

I didn’t even know JET was still around.

I can't even deal with this item description. Air flow restrictions. Really it isn't enough to matter. Gm made the intake tube larger on supercharger cars for a reason. The computer is still going to be the same so no matter if it allows more air how do you get more fuel to correct the afr. Answer is it does nothing. It is a cheap part that is easy to install, and a claim of performance and jet makes money. Much like their throttle bodies that are big money compaired to say a stock 6.2 oh and not bigger or better as claimed. I know this because we had one on a truck that got much dyno time. That came off and stock 6.2 went on the l83.
I promise this does nothing to improve performance. Same as aintake tube on stock vehicle. The air is calculated and adjusted. So you just get less throttle blade open.
If you question this look at the torque based tunes these vehicles have and the pe tables that reduce the power anyways.
If this part has hardware that lies or is different to stock how would the pcm adjust for it? Target afr is set and o2 read that. It can only use pe(power enrichment) or torque management to reduce power. Other settings slip trans as well.

Guys be skeptical... Look for DATA** Speak with Tuners and Folks that have been around these items for decent length of time. Don't ever just accept anecdotal comments or **feelings**. They're not factual and don't provide any evidence to support you spending your hard earned money!

 

 

As far as my experience with JET;

I've purchased the TB and then the MAF sensor.  I did not notice a single difference using one, the other or both at the same time (purchased independently of one another).

 

When Speaking with tuners, (DiabLEW, and local tuners) they all recommended going back to OEM as JET causes issues while tuning. Especially the MAF sensor. 

 

Just my $.02 save your money. If you're out for Performance just buy a Supercharger kit, Whipple, PROcharger or Eddlebrock.  They're all relatively the same price and go on sale during Black Friday (Big time). It will provide a totally different driving experience and jack your HP up significantly without having to upgrade any additional internals/externals. 

 

If you're out for a cool sounding vehicle, just grab yourself an exhaust.

Well I hate to be that guy to have have actually tried this but I have put this exact sensor in two different GM cars a 2017 Silverado and a 2017 Terrain out of curiousity.Now I dont claim to know what it does, How exactly it does it, nor if there is a measurable difference in power on a dyno but for a fact there is a difference in the driving with it on.This is parking both cars then swapping between the stock and Jet sensor back forth many many times and there is always a difference with it on.The best way I could describe is it feels like it tricks the car into having a little more timing and snap at the bottom end but thats it.I would agree either way it is a waste of money because when the cars go WOT the computer will step in to pull back the knock and then there is likely no power difference at all.Then again this type of mod is really no different than throttle controllers and most bolt ons put onto stock trucks.Most of it will make no difference at all in actual power and probably run worse without a tune but people spend the money anyway because it changes the driving experience.Just my .02

So if you don't change computer nothing helps . How about a super tune

the best tune for the money i found, is installing 170 thermostat, disconnecting the TCC function in the trans, pull out the restrictor in the CAI, and activate the power enrichment in the ecu.  this alone will trip the Torque management so you know it makes good power for cheap. total cost about $250  and almost adds 20 hp , requires premium fuel to keep the engine in the high octane advance table, next power upgrade is the E85 sensor, might add 10 hp
