It was a junkyard here in Tampa, Florida
More specifically in Largo I believe. My good friend went and got the ECM back today from them and they still had it so we're very lucky on that end. Apparently this place also does restoration / rebuilds engines I believe. Did you want the actually name of the business? I can ask my friend.

***ECM mailed to bob will update when it comes back and we fire her up.

Hard nut to crack, bob at mefiburn doesnt have unlock codes for 5.7's, at least for TBI 5.7, not sure on yours . so whoever does it will probabaly have to erase it and put a base tune in then tune it in your boat or on a dyno. With the unlock codes, your tune could be unlocked then modified as needed, Smitty
