My throttle body seals were leaking, and o2 housing gasket as well as my uicp.

So I fixed those and came back.

I didn't think it was worth it at first but it is.

Plus the fact that many other tuners do that for free. And charge half that much for tuning. I paid 300 for 4 hrs of tuning. And he changed plugs, a test pipe gasquet ... ect all for free. Just saying. But whatever makes each person comfortable with their tune. That is important so if ffteck did that then everyones happy.
