swiss cheese mod and gas mileage

[TSTONE]

I did the swiss cheese mod yesterday and replaced my filter with the K&N panel type. I was careful not to get on it anymore than normal, or change my driving habits. It seems like I'm suddenly using alot more fuel. Do I need to reset my computer like I did with my 93?

probably so. And after you reset it - the gasmileage might not change because it has to relearn all the parameters. The computer will eventually relearn the system after awhile of driving...but I believe it learns quicker when the battery is disconnected. Also, usually a way to help progress the relearn process is by running it WOT a few times.
