If you're gonna dyno tune it, I recommend a Mustang brand dyno like Coastal uses, because it will load the motor just like it sees on the street.

Its not impossible to street tune, but its not safe either. You'll definitely want someone watching the gauges and running the datalogger while you drive. As far as suggestions for locations, the Howard Franklin bridge or the Causeway bridge late at night would probably be the most convenient and safest.
