Had original 2WFMR installed back in January and it had just short of 1/4mile range (as advertised 1/4 mile). Upgraded a few months later to 2WSSR so I could get the extra range up to 1 1/4 miles. Been using it for several months and decided to check for range. It does not even get to 1/2 mile with unobstucted view. Called Firstech and they sent a new remote and there was no change. Went back to installer and they contacted Firstech and they decided to replace the aerial. That did not work. Dealer called Firstech and they agreed to put in new "brain". Just did that yesterday and no change! The aerial is not blocked by any window tint. The ground has been changed three times it is getting proper juice. My question is, " could there be something in the pcm or electronics of our Impala's that could create an interference issue??
