Just saw that a CT4 V BW with a tune put down a 11.2 quarter at 124 mph at Cadillac Attack in Florida this past weekend. Stock inlet and exhaust. Dont know if they cracked the ECU or are using a piggyback, but the car is going to be a monster with a few tweaks. The blackwing runs 14psi of boost stock, and the tune took it up to 18 or 19psi.
