nonsense Posted May 3, 2011 Share Posted May 3, 2011 I'm trying to figure out which tune to use. I have an 05 LGT with a AVO Panel filter, and STi up pipe (catless). Otherwise all stock. Should I use Stage 1, or Stage 2? Link to comment Share on other sites More sharing options...
ragman Posted May 3, 2011 Share Posted May 3, 2011 Stage 1. You need a Down Pipe to run stage 2. Link to comment Share on other sites More sharing options...
goneskiian Posted May 3, 2011 Share Posted May 3, 2011 Stage 1. You need a Down Pipe to run stage 2. Or you can have the first post turbo cat gutted and you can run stage 2. With the drop in prices of quality after market DP's though, this makes less sense than it used to. Link to comment Share on other sites More sharing options...
