i have a S14 sr20det w/ a garrett 2871r .64 AR, apexi safc and avc-r, Z32 maf, and RS enthalpy ecu tune. I have had it dyno tuned. But when i am on the highway and i get on the throttle, it will boost over the set boost in the AVCR, regarless of how i set up the config(wither its a higher boost level and a low duty or viseversa) and not only does it go over the set boost but it dosnt hold a steady level. It will boost to say 1bar then drop to .7 then up to 1.2 then down to .8, all while my foot is steady on the pedal. Can't figure it out! Any and all help i can get would be great!
