Oh yea haha, '91 TSi, e16g, dsmlink, stock wires, 1 step colder plugs, plx 300, aeromotive FPR, Walbro 255.
I know stoich. for ethanal is richer than gas (what, 9:1?) wont the wideband still read 14.7:1 when stoich.?
we were shooting for 11:1 ratio, I think it was slightly leaner
the car was just pressure tested for leaks and checked out.
