Not bad. I have found with my ECSB to hold the brake firmly, put the tranny in manual mode 3rd gear, let the turbo spool up for a good 6-10 seconds and then let it go. Man it will break the tires loose violently and burn much farther than that and with no power braking. Once when i had hankook dynopro m/s on the back of mine i power braked it up into 3rd and let it go, i went an easy 600' but i had my hands full of steering wheel trying to control it. I damn near piled it up that time and have not power braked it since.
