Well it is more than a chip, as you have to flash the OBDII engine management computer. The answer is yes you can turn it off. There was some track testing I was told about where the C6 with a pair of MT streets ran the 1/4 in 13.30's (no tire spin) after the computer was flashed it ran into the mid 11.00's but the trap speed was about 126mph on both runs. GM is certainly limiting the torque off the line. Must be a liability thing.
