it was between the header and midpipe I just used a extra washer on each side and tightend it up

That was your problem then. Oxygen was getting into your exhaust and hitting the 02 sensor throwing the reading off and the computer was dumping fuel.

you getting this fixed makes me feel better about doing my swap, i have the pi parts in my dorm ready to be installed, but upstate NY i have to wait til most the snow goes away (july), lol, j/k. im bringing my stang up to college after spring break (march 23-ish), then the swap will commence. I still want to see what number you pull with your fixed setup

Yeah ill probly head back to the track next weekend. just some advise get a oil change and a flexible dipstick if need be! I had to order a next day shipping dipstick so I could drive it or just make sure you put it in before the head, although in my case I had to try to get it threw BBK shorty headers.
