I called this place near my house today for prices. $105 an hour with unlimited runs.
My Question is, I talked to the guy that runs the shop and the system they use is WideBand O2 but its in the tailpipe and not in the o2 sesor hole....
Is this not worth doing because it wont be as accurate as closer to the engine ?? there are really limited places to go around here...

Any feedback would be really good

that is an awesome price, at least for my area.

its not as accurate, but they still try and tune for a specific a/f ratio.

 

It will be more accurate if you remove the cat and put in a test pipe. (Did you ever wonder why they call them test pipes?) Make sure you don't have any leaks whatsoever in the exhaust system.
