Looks good

I think you'd like the S2 or S3, from other reviews the low end on these is improved over Stage 1. Also Dinan software is 15% till end of December - you only pay for the incremental difference.

One word of caution - in one of the pics with the stock mufflers removed you can see the vacuum lines hanging down that operate the factory exhaust flap valve. Check and make sure the shop plugged those off so they are not sucking air and dirt which may lead to a check engine light and reduced power.
