I know you can delete codes with the Jb4 Stage 2 but cannot with stage 1. But will a Stage 1 plus a downpipe throw any codes? I ask b/c I plan to get stage one then maybe adding a dp down the line. I'm assuming yes due to the dp alone. Is this correct?

Also, what kind of max power difference can you expect with this combination vs stage 2 + dp + different maps?

stage 1+dp about 325-330whp stage 2 map2+ dp 350-355whp .. based on terrys dyno .. so its about 20-25whp difference which u'll deff feel .. + u can put some e85 and on map7 i'll be about 45-50whp more .. so stage 2 deff worth it over stage 1 if u plan too do dp...

Yep go with stage 2

So nobody knows for sure if stage 1 and a dp alone will throw any codes? I'm assuming the dp alone will, correct?

Yes it will almost certainly throw a code given enough time. Perhaps a carted version wouldn't but cat less will most likely.
