2011 WRX STI fully built..was running great then after a few runs started to miss bad under WOT and 26 Psi..guess I broke something. Crazy thing is that normal driving has improved..only WOT is the issue ..hopeing it was bad gas but ran it all out..maybe bad plug..can not find and vacuumed leaks. As you can see from the vid makes boost no issues as long as not WOT. No smoke..no milk shake..no nothing ..just machine gun at WOT
