My brother-in-law has an '07 classic 1500 ECSB with the 5.3. It's one of those that the dealership put the lift and big tires on to add bling and sold it that way new. He likes the truck and it serves well for what he uses it for. Problem is when the dealership modded it, they just added the bling and didn't address the whole package. It can't get out of it's own way around town and on the highway sucks fuel like it's hooked to a refinery.
For the last 5 years I've done nothing but diesels so I know nothing about the new gassers and can't seem to find the answers I'm looking for. So point me in the right direction. Everything I read says pull the 5.3 and put in a 6.0. That's not what I'm looking for and it's not really an option I care to undertake. I need a forum that does a good job addressing the issues of the 5.3. I know it needs re-geared for the bigger tires. And I know the computer hasn't been updated for the bigger tires. I know there's some kind of torque management issue programmed into the TCM that needs addressed. I'm not looking for all out HP. Just good reliable performance upgrades that will help drivability and mileage.
Any help would be much appreciated.
