Quick Questions for the pulley experts!
I just got my pulley yesterday in the mail and am very anxious to install it. Do I need to get the fuel settings changed first, or can it wait a day or two. Also, if I run on 93 Octane all the time, what should i change the ignition to, if at all? The fuel setting does need to be changed to Stage 2, correct? Any other helpful hints before installation would be great. Thanks!

Nobody has actually published any dyno or a/f ratio results with any of the ECU settings. I would be wary of changing anything until definative dyno testing has been done. If you go by what Renncpe and Kleemann have said in the past, change the fuel corrective to Stage 2 and ignition to 93 Octane. Frankly, I tried Stage 3 and 91 Octane and got misfires, 17hp less and nothing good to show for it (except gas mileage went up about 10%). Kleemann and I ran our cars without any changes for a while with no side effects. It may pay to wait on the ECU changes until more information is available and enjoy your pulley in the meantime.

My settings are the same as Buellwinkle's. No ill effects that can be noticed without instruments. 1000+ miles with the ASP pulley, and still going strong 
As for your case - if you install the pulley first, you can feel fairly safe without flooring your car too often (although you'll be tempted, I know). It's the WOT mode that makes the engine run too lean with the "base" fuel setting.
