can someone look at my tune and let me know what you think? I am new to tuning and am doing my 79 malibu with a 5.3/4l60e combo, 3.73's and 24.90 diamater tires. Seems to have a shift flare on 1-2/2-3 shifts at light throttle. also the vcm was from a 4.8 which I redid the tuning to a 5.3 today and it got quite a bit better but also doesn't seem to have much difference in performance mode. help please
