Gutted Precats / need some info

[FlipRS6]

Just got the eurocharge ECU tune / the MTM TCU tune done on my Rs6... My next venture is to gut my precats, but before doing so i needed some info... If i gut my precats will the check engine line come on? And if so where is a good place to get some 02 simulators.

Yes. And why don't you just have a new file sent from Jerry to delete the secondary o2 sensors?

[FlipRS6]

What do i need to do to get that done?

Just call Jerry and tell him what you are doing.
