8.1 only question

I was just wondering if anyone out there has used this ultrapower ECU? It looks to be geared just right for waking up the 8.1 and gains some MPG.

    You want a quality custom tune for a GM gas engine, check out Black Bear tuning! They are the number tuner for GM gas trucks.

    Looks interesting. I'm of the opinion that if GM thought they could have tuned it to make more power *reliably* they would have done it right from the factory. I've got 182k on the truck now, motor has never been opened.
