The Cold Air Inductions system doesn’t have one either and the Chevy Performance Intake is made by Cold Air Inductions! The only difference in the two is GM has a flash tune for theirs and Cold Air Inductions uses the factory tune.

Thank you for your post.
Nice to give this info.
There are different company in the market, different designs, and every company says: I am the perfect.

My choice was R-F because: it’s make a closed box under the hood. And it has a big filter.

My choice to do a upgrade for it, it’s not a god who made it, it’s not perfect.

There is a thousands of videos in YouTube for people, they did make the own air intake and air tube.

And none of the CAI options except the RF big gulp with a tune on the ZL1 give you more than 5 rwhp with a tune or not. But the sound is nice and you get some nice underhood eye candy.

Very true Fraxum!

There is zero wrong with the RF CAI system and your car. Negative LTFT and STFT numbers is caused by the ECM adding fuel to the mixture in response to an increase in airflow.

RF has done tons of dyno testing as have several other non-affiliated shops, all who have confirmed the RF system will pick up power and there is no real need for tuning on the base RF CAI system (the RF CAI Big Gulp does require tuning) as the ECM can and will compensate for it.

When you added the RF CAI to your car the extra airflow increased the airflow the MAF sees which moved the MAF scale higher in its range. When this happens the extra airflow in the MAF moves the MAF up the scale which then adds more fuel that the ECM can provide when you are at WOT.

By messing with whatever you messed with in your MAF all you have done is skewed the results. Unless you put a wideband O2 in the car and log your runs you have no idea at all what you have done to the fueling much less the WOT fueling.

Care to cite or quote a source of "only giving 5rwhp tune or not"?

The data RF posted when they 1st launched their CAI along with several other independent shops that dyno tested the RF CAI along with several other members have all shown more than 5rwhp gain with zero tuning.

Every time I see someone post a regurgitated internet response of "CAI dont work and only add noise" makes me want to question that persons knowledge of aftermarket performance mods.

My case in point, on the 2008-2013 GM 1500 trucks one person tested a basic CAI system and said there was no gain and it wasnt worth it. Then when the K2xx (2014+) DI trucks launched and the aftermarket responded with CAI kits those same people said there is no gains, the OEM is the best blah, blah, blah....

2 different shops did a shoot outs One shop did theirs all on the same day on the same dyno on the same vehicle with zero tuning. They did the same process of unhooking the battery and changing the CAI out and then the same warm up procedure with 3 pulls.

End result was several of the CAI produced gains, most of those gains were well above 10rwhp. 2 of the CAI actually produced near 20rwhp gains over the OEM setup.

I have personally worked with and dealt with GM's engineering teams and spoke to them about the aftermarket mods. GM has to set a HP goal and then certify that engine for that HP. Can they get more, sure they can. But they have to balance longevity with a wide customer base that wont always take care of the vehicle. They have to meet internal legal requirements that mitigation attorneys suggest along with NVH requirements and several other criteria all while making the end consumers happy across the entire age range of user who will buy that product.

The RF CAI system works, I wish I could have kept mine but once I went with the Procharger I had to remove it from the car.

For how is interesting:

I explained what i have did.
If you understand or don’t , like or don’t, this is my choice and i do what i want.

Make your stock Air intake or aftermarket intake as you wish to.


Feel free to write what you think or guess.

For me; I don’t have more explaining.

Every CAI have own design, and i did mod my car’s CAI as i like.

The thread is all yours now

So when people question what you are doing you get in a huff and move on, sounds about right and par for the course.

Until you properly data log while using a wideband O2 sensor you will never be able to know what the engine is really seeing. All you did was guess on some things and then made a post with possible inaccurate data.

As several of us who actually do mess around with the tuning on these cars stated, you have the STFT/LTFT points backwards. I have read several of your posts since you joined the forums, you have been complaining about your car since you joined the forum between the O2 sensor issue and now the CAI system almost like you are trying to find a problem with it.

And when he blows up the motor there will be another interesting saga

When i blow it, i will buy new. Don’t worry
Just bought it to do some experiments.
It cost just as much as 1 wheel for Koenigsegg.

LOL, here you go:

But in the end people only believe what they want to beleive.

The stndard RF may give a bit more on the ZL1 (untuned here) which did give me 1/10 in the 1/4. At least at first. But over time it went back to stock ETs. I still have the ZL1 RF, anybody need one?

Here i did adjust the filter inside the box .
You know the filter is a circle from in one end and oval in the other end , so the oval side is horizontal position in the next video:

And hear in the next is the old video i did film it. the numbers when the filter turns by 45 degrees ((counter clockwise)):

I have to mention

After reading the data log for the car I did som ( tune ) MAF calibration to be away off any lean points (cells).

I did in my car: (Rotofab without the aluminum bracket inside the air intake tube)
Add to MAF calibration
+1% between ( 0 to 4000 hz)
+2% between (4000 to 8000 hz)
+4 % between ( 8000 to 15000 hz)
I use only on premium fuel. Highest octane in the fuel station.

- This what I did for my car and it runs like a rocket. But please do your tune on your own.

Hope this was helpful
