I think I know the answer before I even asked this but I wanted to throw it out there anyways. In my sig is my mods so far but were all for the most part done by the previous owner. I was told that it does have a chip in it but I don't have any paperwork on it or anything (which from the shape of the car I was surprised to see). I know it does have something done to it because I have the off-road H pipe with quad oxygen sensors. I took it by Dallas Mustang and they told me they could find out what it was but it would cost a pretty penny and was probably worth it just for me to buy a tuner and go from there. Anybody know how I can figure out what it has now or whatnot? Also I use 87 pump gas here as well and have had no problems with pinging or knocking. Am I tempting fate here or could I keep using the cheapo college kid gas?
