When starting to tune a cammed motor swapped vehicle on stock computer what gets changed?for example Mines a 99 4.8 computer with a small cammed 6.0 swap. Do you guys just update cylinder info and fuel injection data then start tuning? Im getting mixed info on my tune. I copied just about everything from a stock 6.0 file to mine and some say thats good but some say to only do cylinder and fuel injection data?
