Hey guys my car feels like it lost some power after I installed a full 3" exhaust from the DP back I got rid of an o2 and it's throwing a code I have the tactrix do I need to have that code turned off so the car is not in a limp mode? Or am I gonna have to get the car tuned to the exhaust ? I someone could let me know that would be awesome

 

having a CEL will usually make the car go into limpmode and run like crap.
A tune is the best mod you can ever make.

 

Your code is probably for the 02 sensor if you removed the cat (it says from the DP back so I am assuming this is correct). It wont run in limp mode with that specific code and doesnt hurt performance, however if the car is over boosting due to the exhaust that could have put the car in limp mode which needs reset. Do you know which code it is?

Also a tune in your case sounds like a requirement. Generally you can get away with an exhaust without a tune but it is definitely not optimal in terms of performance without tuning the car to utilize the new exhaust with less restriction. Also in your case you may need to adjust the boost tables to bring it back in check also.

You next mod if you dont have one already should be a wideband...

 

Yea I'm ordering a wideband here very shortly soon I sell a few car audio things I have laying around and could I still adjust the boost tables like u were saying with out a wideband if that is my issue I'm gonna scan the car here in a few and see what codes and if it is only the code for the o2 my car should be running fine right?
