Ptm question
I have the hypertech power tuning module, if my opti is failing right now, should i wait until i fix that to install it? In other words, will it hurt the car to put it in if it is failing?

If the car is failing why would you try to do something to it that would make more power? Get the opti fixed first, then think about power mods. You won't get any benefit out of any other mods until you get the car running right.
