having it pre-flashed is best thing you can do if you don't have the means to do it yourself or are not experienced.

$2000 is typical price of ecm.

$300-$400 is typical for pre-flashing it.

Having it pre-flashed is cheap insurance against getting a dead ecu or flashing it yourself and truck won't run, wasting hours and days fighting unknowns.

For those with custom programming, run the truck for a good 10 minutes before re-flashing it with any custom programming. Very important.
