Ecm flash

Hi have a question for smarter minds than mine. I’m trying to put zero off in my 08 response lxi. I have found an econtrols ecm that will work with my boat but it is coming off a 08 response lxi 383hp engine and mine is a 340hp engine. My question is would I need to get the 383hp ecm flashed to my 340hp and if so do you know anyone that does this.

    Have you tried contacting eControls support and asking them?
