Hey guys, I have an '03 Suburban that has 218K miles on it with the 5.3 Flex fuel engine.
I really like the vehicle except it needs more power and I have been chasing P codes related to the Drive By Wire Throttle System forever. I posted my "Reduced Engine Power" troubles here.

I don't know anything about tuners or PCM tunes except that they do exist.
I would like to delete the codes that keep causing it to go into "Reduced Engine Power" all the time if possible, and give it a little more performance and/or fuel mileage.
Any information or suggestions would be appreciated. Thanks!
