My question is has anybody installer gm's cold air intake and had the dealership do the tune, and did it proform better, same or worse?

If the intake is installed properly, meaning no gaps and the filter tube is correctly aligned, according to the instructions, it does not matter who installs it. The performance remains the same.

I installed mine but but not sure if I should take it to the dealership to have it tune or leave it alone. Instruction says to have it tune. Wanted to know if it makes a difference.

I misunderstood. I had the tune done on mine immediately after I installed it. I really can’t tell a difference one way or the other. There are a few threads where some folks have done it and says their car ran worse and others like myself who had no issues whatsoever.

Since the tune comes with it, and that’s really why you paid a premium for it over the non-GM branded CAI, then I figured it makes sense to have it done.

Would it hurt the warranty if you installed it but decided not to bring it in to have it tuned?

I installed mine then brought it to the dealer for the tune. I felt no real difference other than maybe a little better throttle response. Hard acceleration sounds better as well.

I had the tune done to ensure my warranty is not voided. Although the same one sold by CAI does not require a tune I assume the GM branded one does not either but I don't want to take any chances.

The CAI CAI which appears to be the OEM of the GM CAI claims about a 10hp increase without a tune. I have it and had dealer do the tune, can’t say I notice anything but a little more intake sound.

Voiding of warranty is case-by-case and unfortunately up to the dealership servicing the car for whatever fault that they’ll try to blame on the CAI not having the requisite tune.

Once again, the tune is included in the pricing for the GM CAI.

There’s no benefit to spending the extra money for the GM branded CAI that comes with the tune and not having the tune done. All you’d be doing is putting yourself in the same position that your post mentions, why risk it?

If you aren’t going to have the tune done simply go with the Cold Air Inductions version, save a few bucks, and call it a day. It’s the exact same as the GM CAI, since Cold Air Inductions makes the GM CAI, but without the tune, GM markup and GM stamp on the lid.

The CAI and GM units are different. The CAI unit is not CARB compliant. To meet CARB requirements the GM unit includes a thin hydrocarbon absorber that changes the airflow characteristics of the metal intake tube. The "tune" that comes with the GM unit is simply a recalibration to account for the different airflow. That's why the CAI unit does not require a tune and the GM unit does. Of course GM recommends that you not remove the hydrocarbon absorber from their units.

[ecko04]

There are 2 versions of the GM CAI:

84315275 - 50 state legal (CARB)
84329125 - 37 state legal (Non-CARB)

GM recommends the calibration update for both, not just the CARB version.

84329125 is being phased out and replaced with only 84315275.

I purchased a 84329125 GM intake from Wildhammer at CF last month. I took it to the dealer today and had it re-calibrated when I had my oil changed. I truly cant tell any difference from before or after it was taken in.

Do you think it would make a difference if it were removed?

I am having GM CAI installed next Friday. A lot of confusion at the dealership(s) as to if the tune comes with the purchase, or if the car needs a tune after installation. One says one thing and the other... Anyway, I chose the dealer that could get the part and will provide a tune. However, they are going to charge me $80 beans total for install and tune. The only reason i am doing this, as it does not sound like it will add any HP, is that GM has sent me a gift card for accessories since they ran me through the wringer on the Rear Diff and the A8 Shudder.
