Been SD VE tuning my TVS2300ed 5.3 and I'm running into an issue where if i go WOT, particularly from a low speed or in low (1st or 2nd) gear the engine doesn't respond. It doesn't quite bog...it just hangs there. If I ease into the throttle i can take it to redline with no issues and when im on the highway in high gear (5th or 6th) i can mash the throttle and the car responds as it should. Looking at the log, i don't seem to be losing boost and i don't have fluctuations in the boost that would indicate belt slip so im a bit lost. Attached are the tune and quick run file. Thanks!
