Axel, we need to define "perform better." And by that I mean not based on someone's butt dyno. Further, and not to beat a dead horse, but we/I also need evidence the Wagner IC is any "better" than stock.

Based on what Renntech told you, it would appear to me they reprogrammed your ecu to take advantage of such add-ons?
