Hello all. I have a coworker wanting to see if i can improve the giddy up in his truck after he took a ride in my 5,3 after i made fueling and some spark adjustments. To be clear i have not made any adjustments to his truck and only will after i scan with a wideband on the unit. I decided to pull the tune file just to see if anything had been done, He did state at one time it did have a 5th wheel in the bed but he has not done anything to it and says that from 0-40 mph its a turd. I know the 5.3s of that time are not known for being power towing monsters. I pulled a stock tune from 06 6.0 on the repository and compared several areas. First i noticed no fueling adjustments, 2nd the timing is toyed with and my big question is the max torque timing table. i noticed that my coworkers table is all over the place. I never had a reason to make any adjustments in that area and i thought it would be fronded upon. should i copy the stock max timing table to my friends table, scan and make adjustments? Any insight will be appreciated thank you.
