It should be noted that the "violent" hole shot he describes is only apparent when you flash the converter hard and really "nail it" coming out of the hole. For daily driving, it can still be very streetable with normal throttle and wouldn't take more than about half hours worth of driving before you got used to it. You might find it even a little "sluggish" with light pedal to be honest....but still oh so satisfying when you punch the loud pedal.
