On a dynojet i made 285 whp @~15 psi with an s14 t28. I have a fmic, 550's, n62 maf, crower 264's, toda flywheel, enjuku 11 lb driveshaft, etc... I have the full slew of bolt ons. My water pump gave out on the dyno that day so I never got to finish. I was expecting to see about 320 whp that day though

Hey, sorry for the delayed reply.

I can't really tell you when it started to lean out. Im going to dyno again before I go to bigger and better things and shoot for some higher numbers on this stock fuel/management setup.

I would assume it just started to lean out slowly from full boost to redline as it starts to take in more air...sooo...I can't really answer that. Also for what it's worth the Wideband source was taking from the muffler so it should be slightly leaner than reading it in the elbow or downpipe.
