Diesel Bombers - new to the forum

Hi, I am new to the forum and just wanted to introduce myself. I am Harley, I live in VA and have a 2000 7.3L powerstroke. I ordered a MBRP 4" muffler delete exhaust that should be in next week. Other than that my truck is stock. Also I picked up a hypertech power programmer III for free from a mechanic from a local ford garage, It came off of a truck that was traded in. He then gave it to me after the dealer took it off. I was wondering if anybody has had one or has any imput about it. Keep in mind it was free so if it works great if not I will get rid of it. Its just temperary until I can get me a 6 posistion TS chip.
