its not the brightest idea to hit it just because it limits it doesnt mean it wont hurt anything say you have a loud system you can actually make your knock sensor think there is a knock in the motor and try to retared your timing and you hit rev limit at 5200 rpms you can throw a rod through your block buddy did that on his 97 dodge had 4 12inch punch 2 subs blew that rod clear outta the block not the greatest of nights weve had
