    How much power will my truck make after these mods?

    Ok so I have a 2002 GMC Yukon 5.3 LM7, I think the stock power rating is 285?, Where do you think I'll be with a few bolt ons like, Shorty Headers, High Flow cats, catback exhaust and a blackbear tune? 145k Miles.

    Shout out to Justin from Black Bear

    Had my 04 Yukon Denali Xl tuned this morning in Somerset, NJ. Justin took his time and tuned her perfectly. She runs almost she like she did when I first bought her in November 2003. It’s a major feat considering she now has 182k miles. Thanks Justin.
