Default will a check engine light automaticlly put my car into limp mode?

I am running a MTM chip and just recently up graded to downpipes and cat back exhaust. I'm pretty sure that the code that sent my check engine light on was the O2 sensor on the cats, since I don't have pre cats anymore. My car does seem a little slower, what does it take to put an S4 into limp mode?

No, it depends what the DTC is.

Default An overboost DTC will cause the car to be slower. That could mean the BOV or the MAF are bad or you

are leaking air somewhere. Just a guess
