Has anyone had luck just leaving the convertor unlocked all the way through on this car? I keep having issues with the car dropping rpms in 3rd and then the car no longer pulls up top and doesn't get above 6K in 4th. My tuner is telling me it's the convertor locking causing the car to bog. The car has a D1X Procharger and that's what it feels like is happening I just find.it hard to believe a convertor locking could bog a car making 1000HP. Am I way off in my assumption? I just recieved a file with the convertor unlocked in all gears. Is this the norm?
