is that a bad idea to install a dp after already being tuned? i asked about exhaust etc and trifecta said id be fine but with the o2 sensor will i just see codes or be hurting my car

 

What did they say about the DP?

There isn't much of a change that the car can't handle if you are changing the DP, if the MAF tune is good then the car will adjust just fine for any additional air-flow and boost is going to stay the same, although it may come in a little quicker and be a little easier to spin the turbo up with the greater flow, this isn't going to hurt anything.

 

havent replied to me but thats what i was thinking too looking for other opinions. thanks for feedback

 

You should be fine! If you bought a catless downpipe for it then It might pop a code. Get a few more bolt ons and a new tune! (im assuming you are an LNF)
