I did not read the whole thread just the first page but i say just go to the guy and tell em i want to see the Eclipse. If he lets you look under the hood then you will know his mods, but if not then look inside the driver side for a boost guage. Also tell him to start up the car and rev it, if you really want to make sure he does that tell him his car looks crappy and tell him something like "I bet you cant do a burn out". then you you can hear the T/C.
