I need a different bit for my dremel to do the cutting of the post. However before I do that I was wondering something. Since the 90 degree bend is removed in that mod what about removing the backing plate on the bend. SO the air can just go straight through. I tried this but forgot to remove reset the computer. It seemed to bog and the 1-2 shift was a bit off, as well as power didn't seem somewaht normal till hitting 4k when the secondaries kick in. So i'm thinking its running rich. How long should I need to leave the neg disconnected and is it safe to leave that plate off? Also how long does it take to relearn the fuel tables about?
