I installed a trans-go shift kit,and it only changes the mechanic parts of the trans.It says you shouldn't use the shift firmness from the hypertech if you installed an aftermarket shift kit.I called hypertech,and they said it only raises the line pressure a little bit.What would be so wrong w/ raising the line pressure up w/ a shift kit.When would you want to change your line pressure,after a tc mabye.
