Jason’s (Dizzy) response was in the original post. Tuners won’t be able to tune out codes, the biggest one that affects our platform specifically is the P0420 for catless downpipes. Don’t even get me started on catless street cars... Tuning isn’t really the issue being pushed at the moment. The reason Subbie guys are screwed is because they delete air pumps, TGV, cats etc.
This is why I am thinking of going with modding a stock downpipe to flow better or hoping COBB manages to get their 400 cel gesi downpipe E.O.d from CARB. They took it off the market though till if/when it does unfortunately so you can no longer buy one now.
