Any one have any thoughts or come across this before? Also, if any of the ESS vendors are online, I'd appreciate any thoughts. I've reached out directly to ESS, but it's a Sunday so I didn't expect an immediate response.
I've never had any issues with my kit except an increased emissions cel, upon which I called roman and they emailed me an updated tune almost instantly! I would assume it has something to do with your install
