I have a 13' R18 Civic and just yesterday i personally installed an RV6 DP and uploaded the starting calibration that Vit sent over for me. Everything seems to be working fine until about 30-40 mins into driving i get a CEL. The code comes up for P0400 EGR "A" Flow just as the title states. I cleared the code to make sure it wasn't some fluke and sure enough about another 30-40 minutes into driving the code re-appears. I'm not too concerned about it as im fairly sure it has something to do with the tune as this code never appeared when I was on a stock tune, if my EGR passages were really clogged it would have threw a code on a stock tune as well. Just wanted to see if anyone has ever had this problem before, for now im just waiting for Vit to return and see what he thinks about it. thank you in advanced !
