Most of us DIY. Depending on your carb you may need to adjust a step or two leaner in jets for Tucson altitude (2500 ft) above Florida's 0 ft. Look for the Holley web site that has lots of videos and information. Pump jet, pump cam, secondary spring (if vacuum)can also lean it out at acceleration. I have a set of jets (Holley from 55 to 65). If you really want to fine tune it, higher temps also call for leaner jets. Timing and cams, headers and air filter all effect end result. Sorry I don't know of a good dyno place. Maybe someone else does.
