some dyno questions..
 

When u dyno the car, to the the A/f ratio@rpm Where do they need to hook the sensor up at on an rx7?

For the wideband most shops use a universal that just slips into the tail of the exhaust (Kind of like when you get your car smoged). For the RPM they usual take the signal it off the plug wires.

But wouldnt have dual catback effect the o2 or no.
