just picked up a viper5000, had it installed and its working pretty good except for a few things. the sensitivity is turned up to the highest on the remote, but i still have to hit my car pretty hard for the warning beeps to go off, and ive shaken my car..still nothing, is there anything i can do to increas the sensitivity? also, i know range is a problem w/ vipers, but im only getting about half a block of range..anything i could do? i was planning on calling the guy tmw about these things.
