Went to the dyno yesterday and can not seem to get tuned out properly. on initial boosting I lean out to a a/r of 14 to 15 until I reach full boost then have no problems with a a/r of 12

I have uberdata for fuel management, 255 fuel pump, 450 injectors. only running 10 psi so I have no idea why I can fix this a/r problem next dyno run Im gong to see if fuel pressure is dropping significantly otherwise i've never see a prob like this with a realtivly small turbo
