think just a retune running rich. sorry to hi jack
ive got problem with white smoke when iam off throttle on a roll mainly going down hills when iam in 3rd or 4th gear well any gear really off throttle i get white smoke coming out the exhaust and smell of burning in the exhaust (cat substrate?)...could it be a leak in the intake pipe of the rear turbo (r32 gtr)?? would this create popping sounds from the exhaust as well when off throttle n cruising?
just had car tuned not long ago at CRD as well, PFC, cams, etc....
edit: doesnt do it all the time, mainly on hot days...car idle's fine and boosting from turbos is fine, so not the turbos...i do find oil in the intke pipes to the rear turbo as i have the catch can setup that way...head ---> catch can ---> intake
