I know on the 5th gen everybody seemed to do the cai mod with little trouble of any kind. I know the LT1 is different but I cant see it being off the charts that sensetive. I provided a link to the Rotofab cai which is very good and it clearly states no tune required...but who knows.

You're right, the values are calculated.

There are two common types of mass airflow sensors in use on automotive engines. These are the vane meter and the hot wire, (which we have). Neither design employs technology that measures air mass directly. However, with additional sensors and inputs, an engine's ECU can determine the mass flow rate of intake air.

Last I heard none of the cold air kits for the LT1 caused a CEL (including the CAI one this is based on). Some definitely threw the MAF tables off which could cause driveability/emissions issues. I'm thinking the mention of CEL is a scare tactic to push the tune and eliminate the possibility of issues down the road.

The article with Al's quote is below.

This unit is identical to the Cold Air Inductions but with a tune. My expectation would be that the tune optimizes for max performance.

"We know when somebody changes their ECM calibration and we know if they changed to a cold-air intake, we can tell all that.

This I would believe. If you look at all the states the GM cai is not legal it makes me wonder what the tune auctually does that the car doesnt adjust to itself. If the tune helps emissions then it should be legal everywhere considering its a factory direct replacement. And a cai isnt going to blow you away with performance anyway.

This assumes that CARB is a rational organization.

CARB is rational, it's just that it's rules are inflexible and maybe overreaching.

The reason it's not CARB compliant has nothing to do with the tune. It has to do with the intake not using the carbon filter pad on top of the intake not being submitted for compliance testing.

I Don't think anyone is reading your reply.
This is PROOF FROM SOMEONE WHO ACTUALLY PURCHASED IT AND LOVES IT. I think no matter what results come back from anyone, dyno test etc. There are still gonna be those our there in denial..Congrats On glad you like bro!!!!!!!

I'm going to duct-tape a chunk of dry ice to the inside of the stock box. That will let in some cool air.

yea, but it'll be mostly CO2 and probably stall your engine. You'd have to find some way to vent the dry ice outside of the intake.

A viable solution would be to just implement a water injection system to cool the air. Then if you want, you could use the dry ice to cool the reservoir, if you're careful not to freeze it solid.

joke fail.

I think it looks great and I texted your picture to several friends. Clean and I like the Chevy Performance tag on it. Warranty with tune means I'm in but will wait until fall now that temps are up anyway.

Ok...so the Demon is advertised as stock even though the crate, with CAI, tune and skinnies,. is provide over the parts counter. Does this CAI counts as stock? ...like other LPO options (6-piston brakes)?

Easy question can you order the vehicle with this as one of the options? If no then it is not stock. Think of it this way Ford offers supercharger kits for the 5.0 should these be be considered stock?
