What chip/tuner is this?

[85yotabox]

I need help figuring out what chip is in my truck i just bought. The truck is a 2000 f250 7.3, 2wd, 6 speed, bully dog chip and gauges. That is what the discription said on craigslist when i went to look at it. the guy who owned it bought it exactly as it was and used it once a month to tow a small car trailer. when i got there i realized it had a k&n intake, 4" lift billstine shocks, 4" turbo back exhaust. so obviously the guy didnt know what he had so im not sure if the chip is actually a bully dog. the switch that is on it has no marking and has 8 positions but after i turn it past 3 it feels like it goes back to stock. Im some what new to the diesel world and just want to know if my chip is any good. any help or suggestions will help.
this is the chip unplugged and the wires just lead to the switch


and this is the switch

You might contact some tuners to see if they can help.

Van Aaken chip. I think Bean's can still reburn those.
