Aaaaaaand the FPR vacuum line popped off somehow. Wideband works perfectly! Car was running 13:1 under WOT with no knock, but it felt like shit. I guess that's what I get for doing too many things at the same time.
On the plus side, I put the original fuel map on that shane gave me and the car runs low 11's perfectly, even after swapping in the aFe filter and perrin intake pipe. Fuel trims affecting WOT are disabled in my ROM, so this setup seems pretty safe to just drop in on an existing tune or even a stock car and (as long as your fpr is seeing boost) shouldn't run lean
