So I have a cold air intake and I replaced it with a vararam intake. I’ve noticed a drop off on the bottom end. But I’ve noticed less power at lower RPM while going slower meaning if I stop at a stop sign and give a quarter to half throttle it is less power than I had with the KNM filter could it be because of my hood delivering more than enough air to the K&N filter compared to now I am only get an air through the front bumper?
Also if you look I modified my fan shroud. I cut it the width of my air filter dropped it down then add that little side pieces to support it so I am getting an air from the bottom and from the top with my old set up. I have a feeling I made a terrible mistake Going with the vararam air intake
The benefits of a Vararam increase with speed. The low speed variable is probably your tune. Also check your MAF for oil buildup on the sensors.
Brand new mass airflow sensor. I also took it to East Coast superchargers and had a tune done based on that air intake going in. That was just a week ago. Literally it runs so much better with the K&N filter could it be the reasons that I am explaining my hood dumps air directly onto the K&N filter so I can’t imagine it’s suffering from air.

The low speed should be the same ,however, it comes down to the tune ,AFR, timing curve and MAF scaling. Sometimes the MAF scaling has to be tweaked . This will also depend on the MAF location , Powerduct or no Powerduct etc...

If you feel any substantial losses between One intake and another you’re either in your own head, or something is now wrong with your car.
Gains felt from cai/exhaust are almost completely mental. That’s why cars with longtubes and stock exhaust make literally the same power as those with longtubes and aftermarket exhaust. My car made literally the exact same power with CAI as it did stock.
Either put it back to stock or get it looked at and make it right.
I think CAI inmost cases are money thrown in the trash. Most factory systems on newer cars are cold air systems.
A few things to consider, first is that seat of the pants evaluations are unreliable, the next is what tune was done for which air intake--K&N or VeraRam. Another is how well is the air pathway after the MAF sealed. First, I have know several C5 owners throughout the years who have added mod after mod and claimed how fast their cars have gone. After a trip to the strip they found their times were nearly identical to stock form. In you case you might be expecting huge gains when they actually are very small. When you change the tune of a car it is usually tuned to to the intake and exhaust system the engine is using. Canned tunes usually get you very close to your target, a dyno tune will tune you for maximum top end performance and a good scan/log tune will give you additional power under peak torque and near max horsepower. From what you are saying it sounds like you have un-metered air entering into the engine (will slow the Vette down) or the wrong tune (many of your PCM tables are competing against one another). Even if you have a very good tune for your system and no unmetered air entering into the engine you are only going to see about10-15 hp gain. If you are drag racing you might see the car consistently run .1-.2 seconds faster, if you autocross you might see better throttle response coming from a corner, if you are HPDE you will see better lap times and more power up to max hp. For those riding down the street, you will probably not see any real results except a louder engine. With you vented hood and opening in the fan shroud, you engine should run cooler and the incoming air will also be cooler and more dense.
Vacuum leak? Weakly connected MAF tubes / adapters? Canned tune vs in person? I hope a tune was not paid for for just a CAI. That $750 could have gone to actual performance parts like a cam and springs or longtubes.
If this turns out to be just a story of SOTP calibration...
It's very possible that you had a tune in it previously that had your throttle settings severely jacked up. There is a tuner or two famous for that. It does not make the car any faster, just makes you think it is because you have to give it less gas to get the same throttle percentage.
PM me your name and I'll be happy to look over your file before and after. I do not normally jack up the throttle settings because we like to just make the car faster, not make you think it's faster, but if that's what you prefer I would be happy to change it back.
Again all speculation at this point, but I would be happy to assist you with this.

I messaged you a couple weeks ago. But you can text me directly 484-725-5722
After you reconnected the battery did you drive around at high way speeds for 40 minutes like the directions said to? You cant just install and immediately go to the track with a tune specd for your last intake. Car still has to get used to the new air flow.
I switched from a blackwing to Vararam last month and all is fine here

I don't run the Vararam anymore, however I did the same as NCVette1 some years back and also didn't notice anything being described by the OP. The car behaved well after installation of the Vararam.

Very pissed off vararam junk
