i am about 95% sure that my kr woes are mechanical in nature. today at 40mph i went 10% throttle and was getting 5 kr degrees. got my wife to sit in the driveway put car in drive and womp the gas. it was reading kr and i looked under the the car to see the exhaust moving down considerably during throttle, about two inches down. i imagine this will cause the headers to hit the swaybar. i replaced the motor mount 9 months ago as well.
so how much should it move? will holding the brakes down in drive and hitting the gas properly mimic the normal driving kr i am seeing?
