I was hoping to get this figured out and not be the 4 millionth guy posting for a little help... but here we are
The current tune has the car starting, idling and purring like a damn kitten at cruising rpms and load. The problem exists when I hit the throttle and begin to build boost. It misses and pops out of the exhaust at the 3200+ RPM range and only baby boost numbers... Mechanically everything is sound... Build specs below, tune and log attached. Wideband will be here in a couple weeks, which is what I need. Just looking for a quick review of the file to call out all the red flags.
