i just put my 4.30s in today up from 3.73s, anyway my speedo is not reading correctly of course, but i have a custom tune on the car..do i need to go back to my tuner to get my speedo corrected or is there a way for me to do it with the SCT plug in?

the tuner should plug in and readjust the speedo, without messing up your tune

who did you get your tune through? is it an auto? if it is an auto, i would get someone to retune it, like brenspeed... if it is a manual, you can either plug it in and adjust it, of return it to stock and then when you go to load the tune again, it will ask you if you want to adjust the parameters... just click yes and then go to gears and change it
