What spacer setup are you running there?

Nice work! Mine has almost the same mods but not yet tuned. Since new mine struggled a lot with the boost reduction issue and often ran less boost than normal, in fact it’s never seen more than 1.2 bar. After I fitted the MST intake it was almost perfect, always running 1.2. However after fitting the exhaust it now runs 0.8 bar most of the time and sometimes sees 1 bar, and only ever 1.2 in higher gears. Is it possible that the remap can disable this functionality in the ECU? It’s really spoiling the fun for me, I feel like I have the slowest yaris in the world lol
