Hey all I have been having an issue with my OBXT surging when cruising. It happens in all gears. Usually around 3k rpm its most noticeable and only if I am holding the throttle in one spot.
The engine is stock except DW65c pump and Tomei FPR (added after the issues began, thinking it was fuel related)
Competition clutch "stock" replacement with SMFW.
LGT suspension geometry conversion and full refresh of bushings and coils front to back.
Today I did some logging and during a cruise the AFR is fluctuating from 11-18 without any change in throttle input. In a 3rd gear pull its leaning out to 20.33 and now it's parked until I can figure it out. I was thinking maybe a post MAF leak but couldn't find any yet.
Anybody have issues with this before? I have been unable to find a thread addressing this.
here are the logs:
