How many miles before getting a tune?

[4seasons69]

Having it broken in on the dyno was another thing I have been thinking about because I have changed a few things from last year and it was never fully tuned last year and I definitely don't feel comfortable messing around with afrs or timing with aem. It just seems most people don't recommend breaking it in on the dyno.

Weather its on the dyno or on the street I just want to make sure it's done right
