As above just getting a stage 1 map with cai and miltek in couple weeks just wondering how many of you has had to upgrade the DV valve ? If that's the correct part I'm thinking of as I had to upgrade my recirv valve on my Vxr after it was mapped as the standard rubber 1 was prone to tearing, I'm not great with cars so please bare with me if I'm confused I'm learning tho haha
