E38 Truck cant figure out lean spot..
I am working on a 2008 Truck for a friend which is not running right and i cant figure out why:banghead:
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?
The tune and a short log attached:
