gas mileage

Yeah, I know it has problems I've seen quite a few posts (around the internet) that deal with this topic. I just haven't had the time to spend a couple hours on the net searching for and writing down the info. I think it's a tuning issue... I need to go over all the sensors and stuff verifying voltages and operation. I'm pretty sure my cats are goners with the car running this rich and I'm equally sure that that doesn't help matters any!

step 2 is to drive it where the ecu uses the 02 sensor, between 1500-3400rpm with light load, over 1psi and it stop using the 02.
step 3 is to make sure you dont have any problems, like vacuum leaks etc

they get better mpg by adding a supercharger? uhm, that doesnt make sense, correct me if i wrong but how?
1. the engine makes more power so you dont have to push the pedal as hard
2. theres more air going thru it, so its leaner

thats too good to be true, supercharger would seem to be one of the best upgrades in a way, but i know it would still get blown away by a mildly upgraded turbo2 (stock turbo2? perhaps, i dont know) or 3rd gen but a good upgrade if it gets 27 mpg!
