i installed a boost guage and an AFR gauge before i changed out the chips. i didn't want too much boost or too lean a mixture. things are pretty good, in my car. it also has an O-ringed head and i think it had work done on the bottom end, too, but i don't know because i haven't had that part of the engine apart. at full boost, ~14.5 to 15.5 lbs, the wideband AFR reads 10.8 to 11.2. i don't know what the guys were doing to lose their head gaskets with the autothority stuff, but i think they may have been doing it wrong. just saying.
