i plugged the wideband into my friend's t3/t4 z6 (huge yeah i know) which was running like ---- and turned out he was leaning out to 16:1 in boost
fmu's are a good way to blow your engine real quick. after seeing that i convinced him to let me plug some 450s in and chipped it with uberdata and it runs like a demon now
