[QUOTE="O4L, post: 2222577, member: 24429"] 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. [URL="https://www.okshooters.com/showthread.php?175340-quot-Reduced-Engine-Power-quot&highlight=suburban"]https://www.okshooters.com/showthread.php?175340-quot-Reduced-Engine-Power-quot&highlight=suburban[/URL] 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! [/QUOTE]
