how can i activate full reverse in the esc without a programming card (dont have time to buy it have it delivered).
Probably a question you should be asking of the people who sell the ESC. But...
I don't know that particular ESC but they usually come with reverse enabled. You only need the programming card to change the rotation so "forward" turns the motor in the opposite direction to normal.
Are you saying you've tested it and it won't go into reverse ? How have you tested it ?

i tested it and it does go backward but not 100% backwards. i checked the speeds with a rpm tachometer. forwards, it runs the expected rpm, reverse, its slower. runs at 60% the speed
Ah yes, you can change the percentage throttle in reverse. It sounds like it defaults to 60. Unfortunately I don't think there is any way to change the program in that particular ESC without the programming card.

How do you active reverse mode with Arduino? Reversing signal or other?
On the sort of ESC we were talking about you just send a signal less than the centre value. 1-1.5ms pulses for reverse, 1.5-2ms to go forwards.
Other methods of driving motors have other ways of reversing the motor.
