Airaid Jr installed. Question about resetting computer

[JennaBear]

Most people don't want to do the DIY mods, as most dealerships will come down ******* something like that.

I would be hard pressed to find someone wanting to hack up their intake box for testing on a new vehicle.

NOT just between stock, stock with a aftermarket air filter and then with aftermarket air filter & intake.

We did do this a few years ago, I will have to find our results....

And these are what were tested:
AEM no filter
KNN
AEM
Stock with KNN drop in filter
Outlaw
GMPP
Stock with Fram airhog

The dyno sheets in info are in Post #33.

I did the Airaid Jr. and also incorporated your airbox mod this weekend. I can feel a "seat of the pants" difference...

THANK YOU ! For sharing this info, there was at least one that disputed this mod.
If you would have done the Airaid Jr first then followed up with the mod after you drove it a little, you also would have noticed the difference between the two.
At least so far no one has stated a "seat of the pants" difference with only installing the Airaid Jr.

I'm glad this worked out for you, when you get around to doing EFI now they will be able to tune for the intake changes you have already made.
When you get the AutoCal you plug it in scroll down to "Read E38 and save then start over and "Read T43" and save then email these files to your tuner so he can write the tunes.
Its pretty simple, especially once you have done this.

I did my DIY mod first and had a few days of driving before I received my AutoCal to start the EFI tuning.
The power increase was pretty impressive with just the DIY mod, even better with the EFI.
When stock the Denali was pretty much a family joke with have not much power, it was pretty gutless.
It made a lot of impressive noise (exhaust sounds) but that was about it.

Now it makes noise and has the power to back it up.

Its NOT testing when you know something works from past experience's.
Beside the dealer can not see the DIY mod, but with the Airaid Jr they can see the intake change and if they want, they can and will make a big deal out of it.
The dealer won't/can't make a big deal on something they don't see.

Not sure what your argument is there. But at this point, we are beating a dead horse. I provided the dyno numbers as you have asked.

 

[D_R_C]

The dynos show the most improvement was gained from changing out the intake piping. That is where the restrictions are, so any upstream changes will have relatively minimal gains. In the end the gains are relatively low.

Don't get me wrong, I am all for DIY performance mods and have done quite a few on my vehicles. Since I am cheap and have little time to work on vehicles I have to be efficient in choosing my mods.

I applaud those who try various things and share . If someone would like to dyno the larger intake hole, versus aftermarket, versus stock that would be great . IMO the results will be similar to the dynos already performed.

To point out something that most are not seeing or even thinking about, I do.
Check out the reduced section for the MAF sensor in the picture below.
Now if that MAF sensor section was a larger diameter coming out of the air box going into the larger diameter intake then you would have a wow difference in air flow.
But it is not larger its the smallest section in the intake system.
Your only going to move so much air flow thru the intake with the smaller section with the MAF sensor which does reduce the air flow.
The aftermarket intake helps, the DIY helps even more.

 

[JennaBear]

The AirAid is not smaller after the MAF, we have pictures of all the intakes we tested here:

http://tahoeyukonforum.com/forum/showthread.php?t=41254

The only thing that would be a problem would be if the MAF housing and the throttle body were two different sizes, which they aren't. The MAF housing on my 2010 is 87mm and my throttle body is 87mm, both stock.

Furthermore, if either were a major restriction, said restriction would be visible at high RPM only, where the engine would be incapable of pulling sufficient air through those items.

As it stands, the restriction for all components combined is a few percent in most cases (measured be engine vacuum) and the largest culprit there is the air filter.

Not sure what your argument is there. But at this point, we are beating a dead horse. I provided the dyno numbers as you have asked.

Unless I missed it I did not see any dyno #'s with something like my DIY mod.
The problem I'm having is you jump on my DIY Thread saying by doing the DIY you won't gain anything or even get the numbers I'm getting, its impossible you say.

Someone has already reported back his findings which was positive.
So now who's beating the dead horse.

I did invite you'all the next time your in Phx look me up and I'll be more than happy to prove you very, very wrong. On a DYNO.

I realize your in the business to sell stuff, but I'm in the business to tell people good DIY stuff that works, sometimes just as good and will save people money. That's my goal in life.


I'm pretty sure I stated the MAF is small going into a larger intake and from the picture its pretty obvious the Airaid JR is larger than the stock. BUT the air flow has already be restricted down to a smaller size with the MAF. If the MAF was a larger diameter that would help more.

 

[JennaBear]

I never said it was not a good mod, just saying that your numbers seemed very off. I also offered up empirical and factual data on how those numbers would be calculated. We have seen quite a few customers with the air box mod. I don't doubt that it is an ok mod, just saying that you had some lofty numbers.

He did report his findings, after installing BOTH an AirAid and the swiss cheese mod.

I actually am not in the business to sell stuff at all, I work for the Dept of Defense, not BBP as many would think. I offer up information in these forums purely to make sure that folks have enough knowledge of this stuff so that they can feel comfortable with their purchases.

Yes, BBP sells a ton of performance parts. But to be honest, I don't even have an intake on my Denali!

I have kept all my posts to you very concise and cordial. I am a scientist by trade and like true numbers and facts to base my decisions off of (not comparing apples to oranges or gas to diesel).

Seeing as how you are older than my parents, I would never disrespect you, but I respectfully disagree with you.

OK then we'll call it Agree to Disagree, and then drop it.

What is the diy mod again?
