Default vararram intalled!!

I installed my vararram intake yesterday. I am pretty sure that if I removed a few more bolts on the car to install this, I could have removed the pistons.

I also cleaned my Radiator (for those that have not done this in a while do it!!) I removed at least 5lbs of dirt,tiny rocks, bugs, and grass..

Today I drove the car on the highway and noticed that at a certain rpm the car would surge? Does anyone else have this problem??
After a while it seemed like it got a little better but I might just have got used to it..

I did not notice any more seat of the pants power, but my z06 was already faster than crap to begin with..

that should settle down a bit as the computer learns.... the more you drive it the more it'll re-learn - to a point...... you may or may not need a re-tune...you probably won't...

You'll need to drive it a while for the LTFTs to adjust to the change in airflow
There's no need for a tune
Excellent mod on these cars

Mine is being done this week with heads, cam, and 3200 stall. I am going to give all of the credit to the intake.

I am also shopping for a CAI intake and am considering the Vararram and power duct - Was it a fairly straight forward install? Also, wouldn't mind some input as to what others think of this system versus others.

Many owners of a ZO6, which has an unscreened MAF, have this problem.If you complete the required drive cyle and still have the surge,you may need to add a screen.

Great intake! I had to take mine on a 100 or so mile trip for the surging to stop. As others said it just needs to adjust a bit.

I thought it was and it was one of my first mods. You will need a high patience meter as you will be removing a few pieces to install it. 3-4 hrs is typical with a break.

It took about 75 miles on mine. I also picked up 4.6mpg going off the DIC.

Mine took less than 2 hours. I guess I got lucky.

5-6 beers and your done!


The surging will quit after a while but it does feel weird! Find a lonely straight stretch of road and romp on it several times....you will SOTP feel the VR! Especially above 50-60!

The screen is not needed. It was used for trucks because the trucks intake path is not straight like the Corvette.


OP, you really leaned the system out by installing the intake. It should "learn" and adjust after you drive it for a while, but you would benefit from having the engine tuned, even if it is only with a handheld programmer.

Oh, I think there are two (maybe it's only one) fuse for the PCM that you can pull and that should reset the PCM and make "learning" a lil quicker.

The added airflow from the Vararam causes turbulence in the unscreened ZO6 mafs for some reason.Adding a screen cures it.Not needed? Why then do LS1's in Corvettes have em?

Would love to see the empirical data that supports your claim. I can only imagine that you received your information from a forum or Google.com search

I can't site my source, so this is only 'hear-say', but I am under the impression that one reason for the screen is that the MAF sensor was utilized on trucks as well as Corvettes, and the truck requires an "air straightener" do to the bends in the air intake system. Personal though: if the screen is so imperative when increasing airflow, then why was it the Z06 that came from the manufacturer without them? The Z06 was the model that utilized an airbox-lid of increased flow capability.

Notice how I write an opinion in a manner that does not suggest it is fact.

It was used on the 2001 Z06 and that is why it was the fastest of all the model years 01-04

Really? The MAF is the single reason why you claim the 01 was the fastest? You're too funny

So nothing else could have contributed to any difference between the model years? Only the screened MAF sensor contributed to your claim that it was the fastest?

At any rate, could you please include citations and sources for your next silly claim?

Do a search here on the forum and you will find MANY owners who had to add a screen to their ZO6 MAF's for just this issue.
