how can i tell if somebody has a chip on my car? and is it possible to tell if they had it tuned with a tuner?

i was at a dyno day and the guy said it looked like my car was setup for a supercharger and i should check for those things, i also have to set my timing back to stock it is advanced 4 degrees and is causing problems with the car

 

also they told me i should adjust my clutch, that its catching too high, can anyone help me with how i would do that?

 

How do you know your timing is advanced 4 degrees?

 

the guy that did the dyno told me it was

 

What did he hook up to your car to tell you it was advanced?
And for the clutch pull up on the pedal this is how you adjust a stock clutch cable

 

i dont know what he hooked up all i know is he said it is advanced 4 degrees what does that matter

and i dont have a stock cable or at least he told me i dont so im wondering how to adjust an aftermarket one

 

It matters because it he didn't hook anything up to your car there is no way tell your car is advanced 4°. I'd be hesitant to trust anything that guy told you. Sounds like he might have noticed you didn't have a clue and just fed you a bunch of crap
Take a picture of the Clutch firewall adjuster and someone will chime in on what one it is and how to adjust it.

 

ill take a picture another time but he said i have a steeda timing adjuster
also he didnt hook anything up to see how much it was advanced he just looked in there and told me

 

idk if this is the exact one but this is what it looks like http://image.automotive.com/f/techar...mage_large.jpg

and i went to a very reputable shop that was highly reccomended by some mustang owners i know so i would trust him with my car any day

 

idk if this is a good enough picture for someone to tell me about how to adjust my clutch but if it isnt ill take a close up one tomorrow.

and can anyone help me in finding out if my car has a chip in it?

you can also see the steeda timing adjustor in the bottom of the pic
and o know that one hose on the cai looks wierd dont worry its not like that, thats how it was before i trimmed it down
