Yes, I was running the same tune (Oft stage 2+ e85) before and after the Tomei header install. So the only thing that changed really was the header itself. It wouldn't be the relearning issue, as the headers have been on for 17k miles now.

Did you upgrade from another catless header? Unless I am remembering it wrong, oft stage 2 is for cars with catless headers, so it would be odd if you were running it with stock headers before.

@Spuds I upgraded from the OEM header. For the OFT V3 e85 tune, it runs the same tune for both catted and catless headers.
