4l80 shifting sluggish and not shiting at wot
well it didnt shift at wot once in 1st(only time i at it at wot) and i think it might have to do with how soft its shifting. just under normal driving you barely even feel the shifts lol. i looked at a corrected truck tune and my line pressure numbers are way lower but that might be cause i have a car i dont know.
Could someone look at my tune and see if anything stands out wrong please?
march 3rd revision.tun
thanks
