Default Air/fuel tuning question

Before I go to a dyno, do I have to make sure they have a wideband 02 or do all dyno's have that.... Also, what is it?

they need to install a o2 bung onto your car (probably around 50-100 bucks) then make sure they do have it as well

from that they can properly tune your car

Most dynos have wideband sensors that can be stuck in your tailpipe. You don't need to do anything to the car.

that depends on the dyno they have
for dynopacks they for sure need to have the o2 bung welded on
for some dynojets its the same way as well
