So I just installed the AMS downpipe and HFC. Shortly after driving I threw the following codes:P1235 P0420 P0234I did remove the wastegate to access some of the bolts, but don't think that is the problem.Will a tune and 02 sensor spacer fix the problem?Thanks!

 

I should probably add that the exhaust is the only mod.

 

nothing? I spoke with AMS this afternoon and they seem to think it is the tune, so I scheduled one. I just want to get some input to make sure the tune goes smoothly.

--------------
You need to tune your airflow tables, disable, or fix a boost leak to fix P1235
You need an anti-fouler or to tune the ECU to fix P0420
You need to increase your boost cut tables or not overboost or disable it to get rid of p0234

It is quite possible that no one responded because these answers have been posted repeatedly. Please search in the future.

 

searched all of them several times....but thanks for your helpful post. Obviously there are suggestions for an anti-fouler and a tune, but I thought I would get whatever input I could.
