Truck is a 2003 1500HD w/ LQ4 and 4L80E. Truck has a K&N CAI w/ filter, stock exhaust manifolds, stock cats, and a cat-back aftermarket exhaust system (dual in single out muffler). Under WOT with 3rd gear commanded for tuning, there seems to be a dip in MAF frequency, hp, torque, inj duty cycle, etc. I have disabled TQ MGMT, adjusted fueling, adjusted PE, adjusted ignition table, slightly increased trans shift pressure, and reduced shift timing. If someone can look at my tune and log file to come up with suggested changes it would be appreciated. Trying to familiarize myself with tuning before I attempt to tune a project 3rd gen camaro with a mildly modded LQ4/4L80E swap. Thanks in advance.
