Re: The 5.3 Blazer build
That is for whatever you need reflashed in it. Oh, and free re-tunes for life, so later when you decide to do a cam, he will just need the cam specs and cam reflash it again accordingly. The PCM's tach output works with aftermarket tach's when they are set to the 4 cyl position.
Best bet is to call and talk directly to Jesse. They are a little slow at answering emails sometimes, but he will talk your ear off on the phone!
