Ok here is an update on my remote starter model compustar 1w900fm .installed on monday this week. got a check engine lite on tuesday had a free check done at auto zone, the read out was running lean on bank 1&2. took truck back to installers and they changed the tac pick-up lead to the tac wire in the dash. They had it on one of the coils on the spark plugs. There was some leak back on the ground causing the lean condition. tech support from compustar told them to do this. So far everything is a-ok now works great locks are on the remote also work fine. what i like about this one is its upgradeable.you can add more features if you want all the way to there top of the line kit.:thumbup:
