Apexi AVCR boost controller, argueably the best boost controller on the market but comes in at £500!! Because my actuator is wound so far out because I get bad creep with my front mount filter, decat and intercooler it seems to come on full boost after 4k rpm!! The AVCR should sort that out but Ideally I need my wastegate ported too, that will be done to the new turbo that I need
