Is it worth $160 for an hour on a dyno w/a wideband O2 sensor? I just installed an AFC and was going to tune it till I was told $160 for 1 hour. Basically I'm wondering if I will actually gain much HP or if its even worth tuning at that price. Would my money be better spent on a different mod and just setup the AFC to compensate for BOV's? Thanks, John BTW: Is there any general settings (%) for BOV compensation?
