I have an 1997 Gs A/T, Its quick though, not slow... LOL
Read the manuel about it, its acts like a boost for some speed.
Well, I've used it a few times when coming on to the freeway and also passing too. It takes it our gear low like 3rd not drive which is like (4)th Does this damage my transmission my step dad said it fuxs it up
IS THIS TRUE AND ALSO, When I onstall my tubo kit w/NX could I used this button for the when I hit the NOS on....
