Insane what these cost vs other systems I've used for other platforms! but my question is how are you guys tuning AFR? Every car I've tuned you need a wideband installed and I haven't seen anyone mention that. How are you getting readings off the stock O2's? Other cars O2 suck as they are not widebands and don't read right. Mostly its the range at which they cannot read. So is another $200 on top of a $1000 tune needed to calibrate correctly?
