I am working on a 2008 Truck for a friend which is not running right and i cant figure out why
It has some really rough spots, especially during rapid throttle changes. The O2's falls on their face and the truck hesitates really bad.
The truck originally had a 5.3 but a 4.8 is swapped in. All tables are copied from a 4.8 file so it should be right.
I have messed around with PE and burst knock to get it to react better, but very little results from this.
I have not touched the "VE" or the MAF tables because in theory it should work as stock.
Hopefully someone have some ideas?
