Well you dont exactly erase it. You really store it in the Edge and then reflash it. Took me about a half hour the first time because I had to load some software, so it all depends on the production date of your truck and the tuner. If you are really worried about a CAI being CARB legal look at K&N I just got off of there web site and the 77 series is legal "CARB EO Number: D-269-29". On another note. I have an Airaid MIT intake on my California truck, it takes about 10 minutes to install and there is only 1 bolt that holds it in place and since it just happens to be in the EXACT same place as the stock intake hold down bolt the stock intake will go back on in about the same time. But to be honest I think if you pulled the badge off of it painted the tops of the screw black you would be able to pass it off as stock. Cool part is that you can buy it with or with out filter.

Looks like this


I am running a drop in K&N with it, it was a little over a$100.00 picked up from summit in Reno since i was up there anyhow, and it seems to help a little. I know its WAY better then stock.

Hell I think you said you lived in Sacramento too. If thats the case you are more then welcome to swing by some time and check it all out. I'm up in Roseville off of 65 and Pleasant Grove I may even pull the intake off and let you try it on your truck. If going for a ride in mine just isn't enough.

 

i'm going to pass on the KN filter because they do mess with MAF sensors and when i put them on my sport trac, it made a good difference on the highway two diff times and then i got worse gas mileage with it on. so i won't use a KN filter anymore.

and by theway, i'm actually in yuba city/ marysville / linda area. i'm not far at all from you. i go to roseville sometimes and go shopping! we're almost neighbors.
