Recently upgraded to a set of PP764 nozzles from Sprint 520s
vehicle has VNT17, 11mm injection pump, 3bar MAP, RC stg4, EGR delete, upgraded SMIC and pipes, turbo back 2.5", BoostValve manual overboost controller
test drove and vehicle has rough and white smoky idle, under WOT would overboost to around 35psi. swapped back the Sprint nozzles and same issue at idle, no more overboost. IQ is set around 5, pump timing is just slightly advanced from center. hesitation is much more noticeable with A/C on.
Any MVB i should check or log
