Weird Problem - New ECM & MPG Loss

Long story short a rodent chewed an injector cable and fried my ECM. I got it replaced and I've lost about 2.5 MPG average since. It's been about a month and I've probably driven 1,000 miles or so. Also got the spark plugs replaced at the same time.

I know correlation =/= causation but the timing seems to indicate something related. Anyone ever heard of anything like this or have any ideas?

Thanks!
