Default Tuner ?

If my car was tuned with Hp and i try to put a FAST tuner on it, what will happen. will it just store my tune now as the original backup? or will it erase my ECM? also does anybody know if the fast tuner will be beneficial to a fully modded car? H/C/I/, long tubes all of it. thanks in advance.

also i am not sure that it was tuned with hp, but it has no chip on it so i'm at a loss.

If you car has internal mods and has been tuned, there should be nothing at all that you would want to do to it with a handheld.

well its on a serious nitrous tune, so i'm looking to take out some fuel, add timing, hand helds would work better for me than anything. i dont want to have to go to a tuner everytime i need to change tunes. and to me there is no use in riding around on a nitrous tune.

I cant speak for the other handheld, but a Predator would let you do that, assuming the tune on there now is not a custom OS or locked for some reason.
