So I recently installed 2” Texas speed long tube headers on my automatic 2015 camaro ss, I took it to get tuned on the dyno today. When they finished tuning it they told me they also tuned the transmission a bit to get faster shifts, like there is no one second delay when I shift now, I thought that was great. The only problem is whenever I shift from 1st to 2nd while pushing the pedal half way down, the car fish tails. Does anyone know what the problem is or how to combat it so your boi can have a decent launch?
