well i will be gettin a dyno tune sometime soon after my cam install .but i have never had any car ive owned dyno tuned

..my question is when i take the car their to have it tuned will i have to have some kind of wideband 02sensor so they can fix the AF ratio or will the shops be able to tune without me having one.I have lt headers no cat and x pipe just if you are wondering and stock 02 sensors

Dynos use a wideband to assist in determining the adjustments necessary to achieve the target AFR. You'll get one or more plots of torque/HP/AFR vs. RPM. Make sure that the tuner doesn't lock the PCM, otherwise only he will be able to make future changes. Negotiate this first.

Dyno will have a wideband. if it doesnt do not let them tune it. Tuning WOT is worthless without a wideband.
