Don't run the intake without the tune. It behaves super weirdly and, for me at least, lost me some power up top, I think.

The more frustrating part is how oddly the e-diff behaves when your MAF values are wrong. The e-diff lockup table must have MAF load or something as an input.

It took me about 45 minutes going slowly and methodically to install it with a few simple hand tools...

Now that you have it installed and had the car tuned (re calibrated is probably more correct) is it worth the money for this mod? Seems like a lot of money for something I think is not going to give you to much of a HP gain or feel by the seat of your pants. I am curious what the outcome is and if you would recommend doing it to others! Thanks in advance.

I think these are pretty generally understood to be mods for looks, sound, and impressing your friends... but not power.

The car only had about 50 miles on it when I installed the intake, so never got on it with the stock airbox... The identical intake from Cold Air Inductions (who makes this intake for GM) claims around an 11 WHP gain... I'm sure you get some additional power, just noting earth shattering... It does sound and look great...

My car came with the intake. Is there any way to confirm if the dealer did the flash when they installed the intake? It's a California car if that makes any difference.

If you bought it new with the optional CAI installed then the dealership would have added the tune!

Someone dynoed it and it shows a 15~20 WHP/WTQ difference. Not a huge gain, but not nothing, either.

I read that thread before and I just have a hard time with it, if it was true why doesn’t Chevy advertise it that way? 455 HP is great but 470 is better. The old cars had options like that and everyone would be ordering with car or as soon as they got one.
My SS came with it dealer installed and was on the window sticker as such.

Your guess is as good as mine, especially considering that it is CARB-compliant so it's road legal everywhere in the States and Canada.

There is a post there implying some CAI's came with turning vanes while others did not. That alone will affect laminar flow and impact the MAF reading. Turning vanes are generally a good idea and reduce turbulence in ductwork.
The OP in that thread is right in thinking the slightly leaner mixture alone could account for the HP increase.


I read a while back that manufacturers typically spend $10-20K designing the intake duct work and calibrating the system on a flow bench. The question is "why bother?" if an L-shaped tube and a cone filter is better (and possibly cheaper).

Wasn’t that part just implemented to cancel out the intake whistle? Mine has one and its position is downstream of the MAF, so no effect on that reading.

you do not need the tune, it is for California emissions.

Been already debunked above. It's for MAF recalibration. I recall someone even publishing the exact MAF recalibration table on this forum.

If you must know how it meets CARB, the manual for mine states that the tube that houses the MAF has a special layer on the inside that absorbs hydrocarbon particles. That is the trick, not the tune.
