Hey all recently bought an 04 1kz-te fitted a boost gauge was boosting to 9.5psi, went and fitted a turbo smart boost controller turned it up and Max it will boost to is 12.5 now at about 2800-3000rpm?
Should these be able to go alot higher? I realise they have a cut out with the ECU at 14-15psi not getting and engine light or anything
