Maybe they do something different on a Mustang dyno.............or maybe the shop is just trying to gouge you because you don't know any better.

Sounds fishy to me though.
dont know much about this shop. i know they are big in the ford mustangs groupos around nashville, as for prices i cant say. never dyno'd a car before. my harley was dyno'd at bike week and runs were 50 each or 3 for 100. not really apples to apples. the reason im going here is its only a few miles from my house. 55 for o2 sensor doesnt give me any warm fuzzies but 50 to weld a bung doesnt sound to far off. at this point i just want the baseline numbers so i can see how the c3 performs
