C7500 GMC and 7.8 l Isuzu diesel
I am new here, so hopefully posting in the right forum.
Bought a 2005 GMC C7500 with a 7.8 l Isuzu engine. Less than 100k on it.
Learned that it came in different power configurations, mine is rated at 215 hp.
Not enough for what I had in mind, but there also is a 300hp option which requires re-programming.
My Isuzu dealer is telling me that no dealer has access to that "upgrade" programming anymore.
Any advise how to get access to it or who might be able to help?
Edmonton, AB, Canada
THANKS!!
