Will a car run richer on the street or dyno?
I can't remember if the car will run richer on the street or the dyno because of load? Which is it?

At a given calibration you will run nominally richer on the dyno since the load approximates a 2600lb inertial mass. Your car is of course heavier, so the load is greater when you are on the street (accelerating the car as opposed to a drum).

Based on what I've seen(on a Dynojet), you'll usually run approximately .2 richer on a dyno than the street. You get a bit more airflow on the road and it leans things out a bit.

This is what happened to me. Dyno tuned great. Got it on the street and running a little lean. Did minor tweaks while running on the street to fine tune the dyno tune and get rid of the KR I got (had none on the Dyno).
Seems to help to do minor tweaks with a load on the car as you have when on the street.
