Hi all, I just bought a 2005 srt6 and am looking forward to doing some basic mods to gain horsepower. I'm having a problem with it though. Some times when I floor it, it doesn't really move that fast almost like it's in limp mode but I don't get any engine light. My tpm light is on though. I bought it yesterday so I haven't had time to look into it yet. Figured I would check here first. Also the horn doesn't beep when i set the alarm or in panic mode. the lights flash though. Is there a relay for that?

Thanks, Pat
